"Perhaps," I put in, "you have a drawing, at least a sketch, some good likeness of her that you can show me?" I realized that our fiction about the bet was by now too tattered to be of any other further use. "Since you say you put in so many hours at it.

Can you draw well?"

The boy looked at me. There was something intrinsically cold, withdrawn, about him. "I can draw. I threw some of my sketches away, but I think there is something. I will see what I can find." He turned away.

"Stay," commanded Lorenzo. "The important thing is, do you know where she is now?"

"Yes, signore, I think I may know." We all stared at him. "In the palazzo Boccalini."

This obviously meant something to Lorenzo and Verrocchio, who exchanged looks. Then the master of the studio demanded of his young apprentice: "How do you know this?"

"I saw her on the street, two days ago, arguing with two young men of that family. They were starting to pull on her arms, and laughing. She was not laughing.

And she has not been back here since."

Verrocchio looked all about him, as if calling on witnesses to this strange behavior. "Yet you said nothing to anyone here about this? Why?"

"No one asked me about it, until now."

Verrocchio glanced at us, then waved the youth away. When he was gone, Lorenzo said to me: "The Boccalini are no friends of my family. And what the boy said may be true, for they have a bad reputation of taking advantage of undefended young women. If she went with them, it may well have been unwillingly. I believe the older men of their family are still at their summer villa, leaving the young gallants unsupervised in town. We will do what we can to find out for certain whether she is there."

Verrocchio, chewing on his lip, had moved a pace or two away; he was not anxious to take part in these intrigues. At this point the young boy came back, lugging a fairly large wooden panel. "The little sketches are all gone," he said laconically.

His master took the painting from him and held it upright on a table, in good light. A twelve-year-old has done that? was my own first reaction, even untutored as I was in the difficulties of the art. For once, I think, Lorenzo's judgement was the same as mine; he scowled intensely and murmured something. Verrocchio, who must have seen the panel before, still sighed faintly with what sounded very much like envy. He s.n.a.t.c.hed up a small brush from the table, and hastily flicked in his signature across a lower corner where part of the background had been finished.

He sighed again. "Yes, this is she, Signore Ladislao, an excellent likeness. From this you may know her. If she is where the boy says she is, I pray Jesus and San Lorenzo that you may bring her safely out. If that is what Your Honor really wants to do."

Lorenzo was still marveling at the painting in silence. Then he asked: "The boy really did this?"

The master nodded. "Indeed he did, Signore Lorenzo. I watched with my own eyes."

What impressed me most, at my then primitive level of artistic judgement, was of course the marvelously lifelike character of the face, which like most of the figure was completely finished; parts of the background, as I think I have mentioned, were still not done. With this face before me, I felt I must know the model at once if ever I saw her in the flesh. And this suggested to me another point: such a perfect, breathing likeness, if allowed to remain here, might someday serve as evidence in the hands of King Matthias's enemies, proof that his sister had indeed once been here and posing.

"I would like to take this painting with me," I said, reaching for my purse once more. "What is its price?"

But this time the master of the shop would have none of my gold. "Please, signore, you will honor me by accepting this trifle as a gift." Verrocchio made the offer quickly and easily; I am sure he calculated that in the long run he would not lose by such a gesture, which ought to bind him closer to the Medici in friendship; and, anyway, the gift was not all that expensive. Not in 1464, though within only a few decades the value of ready-made art from Florentine studios would increase tremendously.

"It is only the work of a novice, signore, though he is gifted beyond-" Verrocchio broke off, catching sight of the boy still standing nearby, silently attentive. "Back to your work now, Leonardo."

Chapter Seven.

So.

It may be that some of my readers, equipped with good memories or else forearmed by a fortuitously recent reading of some art history, antic.i.p.ated the little revelation at the previous chapter's end. But before these readers congratulate themselves too heartily, let them consider why none of those supposedly expert folk involved in the art auction uttered that most potent name. Why, barring one hint by Ellison Seabright, there has not been even the most tentative suggestion along that line. Two points awarded for the correct answer, and more on the subject later. For the moment let it suffice that the reader has now caught up with Mr. Thorn in this much at least: that Magdalen was definitely not a Verrocchio, worth perhaps the quarter of a million dollars or so that Ellison Seabright paid for it; it was instead a genuine Leonardo da Vinci, heretofore unknown to the experts as such, but if its origin could be verified worth easily twenty times that much.

The announcement of the missing aircraft caused Mr. Thorn to cut short his visit to the Seabright mansion as soon as he politely could-which, under the circ.u.mstances of confusion prevailing there, was not long. He took his leave without offering his host any further revelations of his own about the painting. He had not been about to provide that gross, half-clever criminal with any very truthful revelations anyway. The two of them vaguely agreed that they would talk to each other again sometime and with that matters between them were left hanging.

Driving his rented Blazer back into the more plebian regions of the city, Mr.

Thorn felt unhappy for several reasons. First, the painting was once more out of his reach, gone again, somewhere, where he could not even look at it. Second-or perhaps really first-it is always a painful experience, that dawning realization that one has underestimated an opponent. That first moment when the placidly grazing prey turns suddenly, baring its own fangs, unsheathing its own sharp claws . . . and, perhaps thirdly, perhaps worst of all, is the suspicion that one has finally grown old, become ineffectual through overconfidence.

Mr. Thorn, still determined of course to have his painting, but denied it, and realizing now that he did not even know who his true adversary was, would have liked to go back in time two days, and start over again in the auction room. That being impossible even for him, he decided to do the next best thing, which was to come as close to starting over as he could.

Sighting a public phone booth, he stopped and made a call. Twenty minutes later he was ringing the front doorbell of a modest house on an anonymously modest Phoenix side street.

Robinson Miller, eyes full of subtle suspicions, appeared inside and let Thorn in.

At Miller's feet a small dog, on getting his first whiff of the visitor, yapped once in extreme surprise, and then was still. Behind Miller in the living room was the sofa that Mary once had mentioned, looking indeed as if it might have spent part of a long and adventurous career inside a Salvation Army store. Mary herself was just rising from its sagging cushions. Tonight her jeans had been replaced by shorts, revealing legs quite as attractive as Thorn had expected them to be. She wore a blue vinyl vest, doubtless because there was no bra beneath her blue T-shirt. With her usual eagerness for any new development, she greeted the visitor more freely than Miller had. "This is a surprise, Mr. Thorn. Glad to see you. Something's happened, hasn't it?""Yes. Though I am not sure exactly what." Thorn took the offered armchair, a place of honor that got the main benefit of the laboring window air conditioner. He declined well-intentioned offers of coffee and beer, and looked calmingly at the small dog who was edging close to offer worship. To the humans he related the essentials of his visit to the Seabright house.

Mary was quite as upset as Thorn had been to hear about the missing plane, though her disquiet had a n.o.bler basis. "Then the plane is really down? That's bad.

How many people were on it?"

"Oh, I am sure that by this time it is down, somewhere. I gather that it carried only the pilot, a man named Gliddon. A search is to be started in the morning."

"Gliddon," said Mary, and made a face. "I didn't like him." Still her dislike hardly seemed to make any difference in her concern over the pilot's fate. "When I lived at the house he was always in and out, though I never knew what he did. It must have been some kind of work for Ellison."

Robinson Miller said to Thorn: "Do I understand you to mean that you think the plane didn't really crash?"

"Correct me if I am wrong," said Thorn, "but I believe that the land between here and Santa Fe is somewhat spa.r.s.ely populated?"

Miller nodded. "Five hundred miles of nothing."

"Mountains, deserts, some forests," Mary amended. "Late last spring two Air Force planes from the missile range at Alamogordo were lost. They crashed right out in the open and in spite of a big search it was months before the wreckage was found. At least it's not winter now. I suppose if Gliddon survived a crash in the mountains he's got a chance."

"Somehow," said Thorn, "I have little doubt that he survived."

Mary looked puzzled; she didn't get it yet. Miller said: "I suppose Seabright was having a fit. Though not over the missing man, of course."

Thorn nodded. "He was going through the motions of one who is, as you say, having a fit over some lost property. Barking orders, phoning hither and yon, demanding explanations, demanding action. But I . . . have had some opportunity of observing humanity under various kinds of stress. And I am sometimes able to see through efforts at deception. And-this is why I have come to talk to you tonight-I think Mr. Seabright was not truly surprised by the news that his masterpiece and his aircraft and its pilot were missing. Indeed, I suspect that one reason I was invited to his house tonight was to provide him with a neutral witness, able to testify to his surprise and his dismay."

Some of Mary's old fierce delight quickly returned. She thumped the arm of the battered sofa. "I believe you!" she cried. "He's pulled another trick! He's getting away with it again!"But Miller was frowning, shaking his head. "The suggestion being, I suppose, that Seabright is somehow spiriting the painting away into hiding by faking a plane crash. But he's just bought it and paid for it. Why the h.e.l.l should he steal it from himself?"

Thorn had his ideas on that subject. But he said nothing for the moment.

"Insurance money!" Mary pounced.

Her lawyer was still shaking his head. "No, I don't think so. That kind of thing isn't easy to get away with-"

"Neither is murder, but he got away with killing Helen and Del."

"-and anyway, since the painting was being carried on his private aircraft I doubt that any insurance coverage on it would be in force." Miller's gaze focused suddenly on Thorn. "You're not from some insurance company, are you?"

"No," Thorn said patiently. "I am a collector, as is Seabright."

A few feet away, in the kitchen, the telephone began to ring. Miller got up to answer it.

"Mary." Thorn looked at her intently. "Why did Delaunay give you that painting?"

His gaze did not bother her. "Why? I told you. Out of grat.i.tude, for my helping Helen. He was that kind of a guy, I guess. He knew I'd sell the painting, I'm sure. He just wanted me to have some money to use, helping other kids."

"You say you think Ellison knew about this gift? How can you be sure?"

But Mary was looking toward the kitchen doorway. Miller was standing there, rather like some interviewer with a microphone, holding out toward Mary the yellow telephone receiver on its helixed cord. But the look on his face was that of a man in shock, and Thorn got to his feet.

"Who? What?" asked Mary vaguely, standing also.

Miller licked his bearded lips. "She says . . . she's Helen."

There was a pause in which no one did anything. Then Mary sprang forward. In a moment she was holding the phone pressed against her disheveled hair. "Who is this? If this is supposed to be some kind of a joke, it isn't . . ."

A feminine voice at the other end of the connection had begun to answer. It was a quiet voice, and its tones were mottled and distorted by an imperfect connection somewhere, and at first Mr. Thorn could not make out the words. But Mary could, and they had an immediate effect. Her face lost color, and her hand holding the receiver slumped a little. "What?" she asked weakly.

The voice at the other end made itself louder. Now both men standing by in the kitchen could hear it well enough to distinguish words. "Mary, this isn't any joke. It's me. I can't come back now, it's too dangerous. Anyway, I don't really want to.

Everything's fine for me the way things are. But I wanted to talk to you. You're my best friend, Mary." Mr. Thorn, listening hard, thought there was a certain dazed quality in the voice; a disconnection from present reality, as if it might be reciting lines learned for a play.

"Helen? What do you mean, dangerous?" Mary's own voice now sounded no less dazed.

"Why? Where are you?"

"You know why, Mary, if I come back he's going to try to kill me again. Look, I wanted to tell you, Mary, I'm sorry about running away again, after all your work with me and all. But there was nothing else for me to do. Please don't try to look for me again, this time I'm gone for good."

"Baby, if this is really you . . . you tell me not to look for you? How can you call me up like this and say a thing like that?"

"You always said you wanted me to have a happy life someday. So now I'm going to be able to have a happy life. So let me alone."

Miller stood beside Mary where she sat in a kitchen chair. He was slowly bending over her, getting his ear closer and closer to the phone in her hand; and meanwhile his eyes squinted, as if he strained to see something in the far distance. Thorn waited motionless in the kitchen doorway, and he also was listening very carefully.

Mary was starting to recover from her first shock. "Listen, if this is Helen speaking . . . if this is Helen, tell me who was killed? Whose body did I stumble over in the dark?"

"There was a girl you didn't know about in the house that night. A girl named Annie, just a runaway from somewhere, she didn't count. Only Uncle Del knew that she was there, and he was killed too . . . but Mary, I don't want to talk about all that any more. I've found someone who I thought was lost to me forever. We're going to do real things, and it's all going to be okay. He's going to put me in real movies.

Someday."

"Real movies? What do you mean, you've found someone? Who? Where are you?

Helen, this can't be you."

"It's me, Mary. Remember what you once told me, about something you said you'd never told another soul? About you and your boy friend in Idaho? Want me to play that back to you now?"

"Oh my G.o.d." Mary turned still more pale. "My G.o.d, it is you, baby."

"Not your G.o.ddam baby." The distant voice turned petulant. Still a poor contact somewhere in the wires distorted it. "Just let me alone, please. Oh, Mary, I'm going to be so happy."Mr. Thorn, listening, had doubts.

"Helen? Tell me where you are?"

"Goodbye, Mary." It was a lament, a ghost's farewell.

"No, Helen. Wait. Where are you? Helen?"

A click; what connection there had been was gone. Mary talked into nothingness for a few seconds, and jiggled the switch at her end of the line. After that she could only hang up too.

Then she lifted a dreamer's face to the two men. "You heard her. It was her. What do we do now?"

Miller appeared unconvinced. "It did sort of sound like her voice," he admitted.

"Not that I ever talked to her that much, but . . ." He had to pause to clear his throat.

"If that really was her, if Helen's really still alive, do you know what that means? That masterpiece that Ellison Seabright just paid for is really still her property. In the legal sense, I mean," he hastened to add when Mary looked at him.

"Even if Seabright has paid for it?" Thorn asked.

"Absolutely. No question about it. There'd be a devil of a legal and financial mess to untangle. But the painting would have to be held in trust for Helen, as per Delaunay's will. a.s.suming he's really dead. Wow," added the lawyer, looking at Thorn. "And the painting was on that plane."

"The matter of the missing plane," said Thorn, "is now perhaps explained."

Miller nodded slowly. "If Helen is still alive, and Seabright somehow found out about it, he'd then have a good motive to get the painting out of the way. Maybe sell it secretly; there are collectors who would buy."

Mary for once was not delighted to discuss villainy. She slumped in the kitchen chair, not looking like her usual self. "Rob, shall we call in the police and tell them about the call? How are we even going to start looking for her if we don't do that?"

"Indeed," put in Thorn, "how are we to start looking in any case, whether the police are notified or not?"

"Then you advise against calling them?" Miller was fumbling nervously for his pipe.

"My advice is that we first take thought: What exactly can we tell the authorities, and what will they believe? All three of us heard someone on the phone, but which of us can swear convincingly that it was Helen? Certainly not I, who never heard Miss Seabright's voice."

Miller, having found his pipe, held it in his hand forgotten. "I did-a few times. But I couldn't honestly say. Mary?"

Mary had her face down in her hands now. "Maybe . . . I don't know. Maybe it could have been someone else. I saw Helen lying on the floor in the Seabright house, dead. All shot to pieces."

Thorn asked: "You recognized the victim's face?"

"Her mouth was almost gone, her lower jaw. I never realized till then that guns did things like that. Her hair . . . it looked like Helen's hair. I a.s.sumed it was Helen.

Everybody did. It never entered my mind that it might not be her, because I never had any idea that there could have been another girl in the house. 'Annie.' Whoever it was on the phone just now said 'Annie'. Did you hear?"

Thorn and Miller both signed agreement. Mary went on: "It's crazy. I don't know any Annie, and I don't believe there could have been another girl. Dressed in Helen's robe?"

Thorn prodded: "But is it not possible? Some runaway, perhaps, being given shelter? That only Helen and her uncle knew about?"

Mary hesitated. "Delaunay would've told me, if he'd been doing that. Let me think about it. It's not absolutely impossible, I suppose."
