I was watching her closely, and she seemed genuinely perplexed. "Are you trying to threaten me in some way? You sound as though you were."

"The word is warn, Mrs. Blackwell."

Her voice sharpened. "Has something happened to Mark?"

"Something has happened to Ralph Simpson and Dolly Stone. I think both those people were known to you."

"Dolly Stone? I haven't even seen the girl in years."

"I hope you can prove that, because Dolly was murdered last May."

She lowered her head and moved it from side to side, as if she was trying to dodge the fact. "You must be joking." She stole a look at my face and saw that I was not. "How? How was she murdered?"

"She was strangled, by unknown hands."

Isobel Blackwell looked at her hands. They were slender and well kept, but the knuckles suggested a history of work. She ma.s.saged the knuckles, as if she might be trying to erase the history.

"You surely can't imagine that I had anything to do with it. I had no idea that Dolly was dead. I was was quite close to her at one time-she was virtually my foster daughter-but that was years ago." quite close to her at one time-she was virtually my foster daughter-but that was years ago."

"She was your foster daughter?"

"That may be putting it too strongly. Dolly was one of my projects. The Stones lived across the road from us, and I couldn't help noticing the beginnings of antisocial tendencies in the child. I did my best to provide her with an example and steer her clear of delinquency." Her voice was cool and careful. "Did I fail?"

"Somebody failed. You sound a little like a social worker, Mrs. Blackwell."

"I was one before I married my first husband."

"Ronald Jaimet."

She raised her brows. Under them, her eyes appeared strangely naked. "Suddenly you know a great deal about my affairs."

"Suddenly your affairs are at the center of this case. When I found out tonight that you knew Dolly Stone and her parents, it knocked most of my ideas sideways. I'm trying to work up a new set of ideas, and I can't do it without your co-operation."

"I'm still very much in the dark. I'm not even sure what case we're talking about."

"It's all one case," I said, "Harriet's disappearance and Dolly's death and the murder of Ralph Simpson, who was stabbed with an icepick-"

"My icepick?" icepick?"

"That's the police hypothesis. I share it. I'm not accusing you of doing the actual stabbing."

"How good of you."

"The fact remains that you knew Ralph Simpson, you were almost certainly aware of his death, and you said nothing about it."

"Is this the same Ralph Simpson who worked for us at Tahoe in the spring?"

"The same. A day or two after he left you he was stabbed to death and buried in the back yard of the house you used to own in Citrus Junction."

"But that's insane, utterly insane."

"You knew about it, didn't you?"

"I did not. You're quite mistaken."

"There's an account of the Simpson killing on the front page of the Citrus Junction paper in your sitting room."

"I haven't read it. I take the paper, to keep track of old friends, but I'm afraid I seldom look at it. I haven't even glanced at it this week."

I couldn't tell if she was lying. Her face had become a stiff mask which refused to tell what went on in the mind behind it. Her eyes had veiled themselves. Guilt can effect those changes. So can innocent fear.

"You have sharp eyes, don't you, Mr. Archer? Unfriendly eyes."

"Objective eyes, I hope."

"I'm not fond of your objectivity. I thought there was a-degree of confidence between us."

"There was."

"You put that emphatically in the past tense. Since you've been operating with my money, operating on me me in fact, I would have expected a little more tolerance, and sympathy. You realize my connection with Dolly proves nothing whatever against me." in fact, I would have expected a little more tolerance, and sympathy. You realize my connection with Dolly proves nothing whatever against me."

"I'd be glad to see that proved."

"How can I prove it?"

"Tell me more about Dolly. For instance, what were the antisocial tendencies you noticed in her?"

"Must I? I've only just learned of her death. It's distressing to rake over the past under the circ.u.mstances."

"The past is the key to the present."

"You're quite a philosopher," she said with some irony.

"I'm simply a detective with quite a few murder cases under my belt. People start out young on the road to becoming murderers. They start out equally young on the road to becoming victims. When the two roads intersect, you have a violent crime."

"Are you suggesting that Dolly was a predestined victim?"

"Not predestined, but prepared. What prepared her, Mrs. Blackwell?"

"I didn't, if that's what you're thinking." She paused, and took a deep breath. "Very well, I'll try to give you a serious answer. I didn't, if that's what you're thinking." She paused, and took a deep breath. "Very well, I'll try to give you a serious answer. I was was concerned about Dolly, from the time she was four or five. She wasn't relating too well to other children. Her relationship with adults wasn't right, either, and it got worse. It showed up particularly in her contacts with my husband. Dolly was a pretty little thing, and her father had treated her seductively and then rejected her, It's a common pattern. The Stones aren't bad people, but they're ignorant people, lacking in insight. They were our good neighbors, however, and Ronald and I believed in helping our neighbors as best we could. We tried to provide Dolly with a more normal family constellation-" concerned about Dolly, from the time she was four or five. She wasn't relating too well to other children. Her relationship with adults wasn't right, either, and it got worse. It showed up particularly in her contacts with my husband. Dolly was a pretty little thing, and her father had treated her seductively and then rejected her, It's a common pattern. The Stones aren't bad people, but they're ignorant people, lacking in insight. They were our good neighbors, however, and Ronald and I believed in helping our neighbors as best we could. We tried to provide Dolly with a more normal family constellation-"

"And yourselves with a daughter?"

"That's an unkind remark." Her anger showed through her mask. She forced it back. "It's true, we couldn't have children; Ronald had a diabetic condition. I'm also aware of the ease with which good white magic turns into bad black magic. But we made no attempt to take Dolly from her parents, emotionally or otherwise. We merely tried to give her some things they couldn't-books and music and recreation and the company of understanding people."

"Then your husband died, and you moved away."

"I'd already lost her by that time," she said defensively. "It wasn't I who failed Dolly. She'd begun to steal money from my purse and lie about it, and she did other things I prefer not to go into. She's dead: nil nisi bonum." nil nisi bonum."

"I wish you would go into the other things."

"I'll put it this way. I wasn't able to protect her against degrading influences-I only had a part of her life after all. She ran with the wrong crowd in high school and picked up gutter ideas of s.e.x. Dolly was already mature at the age of fifteen."

She didn't go on. Her mouth was grave, her eyes watchful. It was possible, I thought, that Dolly had made a play for Ronald Jaimet before he died. It was possible that Jaimet had fallen for it. A daughterless man in middle age can take a sudden fall, all the way down to the bottom of the hole. It would be a suicidal hole, but suicide came easily to a diabetic. He simply had to forget his dose and his diet.

Being a murder victim came easily to a diabetic, too.

"You have that look again," Isobel Blackwell said. "That objective look, as you call it. I hope Im not the object of your thoughts."

"In a way you are. I was thinking about Ronald Jaimet's death."

"Apparently you've come here tonight determined to spare me nothing. If you must know, Ronald died by accident. And incidentally, since I think I know what's on your mind, Ronald's relations with Dolly were pure-wonderfully pure. I knew Ronald."

"I didn't. What were the circ.u.mstances of his death? I understand Mark was with him."

"They were on a pack trip in the Sierra. Ronald fell and broke his ankle. What was worse, he broke his insulin needle. By the time Mark got him down the hill to Bishop, he was in a coma. He died in the Bishop hospital, before I could get to him."

"So you have the story from Mark."

"It's the truth. Ronald and Mark were good friends as well as cousins. Ronald was the younger of the two, and he'd always admired Mark. I could never have married Mark if that hadn't been the case."

Under the increasing pressure of my questions, she seemed to feel the need to justify the main actions of her life. I brought her back to Ronald Jaimet's death.

"Diabetics don't usually go on pack trips in the mountains. Aren't they supposed to lead a fairly sheltered life?"

"Some of them do. Ronald couldn't. I realize, I realized then, that it was risky for him to expose himself to accidents. But I couldn't bring myself to try and stop him. His annual hike was important to him, as a man. And Mark was there to look after him."

I sat for a minute and listened to the echoes of her last sentence. Perhaps she was hearing them, too.

"How did Ronald happen to take a spill?"

"He slipped and fell on a steep trail." She jerked her head sideways as if to deflect the image of his fall. "Please don't try to tell me that it was accident-p.r.o.neness or unconscious suicide. I've been over all that in my mind many times. Ronald had a great sense of life, in spite of his illness. He was happy in his life. I made him happy."

"I'm sure you did."

She went on stubbornly, justifying her life and its meanings: "And please don't try to tell me that Mark had anything to do with Ronald's death. The two men were deeply fond of each other. Mark was like an older brother to Ronald. He carried him on his back for miles over rugged trails, back to the jeep. It took him most of a day and a night to bring him down the hill. When Harriet and I finally reached the hospital-she drove me up to Bishop that day-Mark was completely broken up. He blamed himself for not taking better care of Ronald. So you see, you're wandering far afield when you suggest that Mark-"

"The suggestion came from you, Mrs. Blackwell."

"No, it was you."

"I'm sorry, but you brought it up."

"I did?" She dragged her fingers diagonally across her face, pressing her eyes closed, drawing down one corner of her mouth. Her lipstick was smeared like blood there. "You're probably right. I'm very tired, and confused. I only have about half a lobe working."

"It's the chloral hydrate," I said, thinking that the drug had some of the properties of a truth serum.

"It's partly that and partly other things. Before you arrived, I had a very wearing hour with Harriet's mother. Pauline flew all the way from Guadalajara to find out what had happened. I didn't know she had so much maternal feeling."

"What went on in that hour?"

"Nothing, really. She seems to blame me for the family trouble, and I suppose I blame her. Someday, in the brave new world, we'll all stop blaming each other."

She tried to smile, and the faltering movement of her mouth charmed me. I would have preferred not to be charmed by her.

"Someday," I said, "I can stop asking questions. As it stands, I have to go on asking them. What kind of a houseboy was Ralph Simpson?"

"Adequate, I suppose. He worked for us such a short time, it's hard to say. I don't like using servants, anyway, which is why we have only the one living in. I'm accustomed to doing things for myself."

"Is that why Simpson was fired?"

"Mark thought he was too familiar. Mark likes to be treated as a superior being; Ralph Simpson was very democratic. I rather liked it. I'm not really used to the stuffy life." She glanced up at the ancestors.

"I heard a rumor at Tahoe that Ralph was fired for stealing."

"Stealing what, for heaven's sake?"

"It may have been a topcoat," I said carefully. "When Ralph got home from the lake, he had a man's topcoat which he told his wife was given him. It was brown Harris tweed with woven brown leather b.u.t.tons. One of the b.u.t.tons was missing. Do you know anything about the coat?"

"No. Obviously you do."

"Did your husband ever buy clothes in Toronto?"

"Not to my knowledge."

"Has he ever been in Toronto?"

"Of course, many times. We pa.s.sed through there on our honeymoon last fall."

"This coat was bought from a Toronto firm named Cruttworth. Did your husband have dealings there?"

"I couldn't say. Why is this topcoat so important to you?"

"I'll tell you if you'll let me look at your husband's clothes."

She shook her head. "I couldn't possibly, without his permission."

"When do you expect him back?"

"I don't believe he'll leave Tahoe until Harriet is found."

"Then he may be there for a long time. The chances are better than even that she's dead and buried like Ralph Simpson, or sunk in the lake."

Her face was ugly with dismay. "You think Burke Damis did this to her?"

"He's the leading suspect."

"But it isn't possible. He couldn't have."
