With Roger's departure, and Beverley's return, the three women could talk with freedom, especially after Mrs. Sands' announcement to the butler that he would not be needed to serve dinner.

Miss Blackburne reiterated that she knew nothing of the envelope. She had had no thought for anything except the pearls. Their loss put her into an embarra.s.sing position unless Mrs. Sands intended informing Mr.

Sands and the police at once of what had happened.

"I saw by your face you didn't want me to speak when your husband came in," she said to Beverley, "so I hedged, and did the best I could without lying. I realized that you would want to be the one to break the news. But I suppose you have told him now? He'll send the police, or some private detective, won't he, to take evidence while I'm here?"

"I do want to get them back," Beverley answered. "But I haven't told my husband, and we can't have the police, or even a detective. That must seem not quite fair to you, Miss Blackburne. Whatever happens, you shan't suffer, I promise. I believe I know who has taken the pearls. If I'm right, it isn't exactly a theft. Perhaps if I go the right way about it, I can get them again. What's the good of worrying my husband, when in a day or two there may be nothing to worry about?"

"M-m-m," muttered Miss Blackburne, "I think you're wrong, Mrs. Sands. I have a feeling that Mr. Sands suspects."

"That the pearls are gone? How can he?" Beverley cried.

"I don't know, I only feel," the little woman repeated.

As the two had talked, Clo watched Miss Blackburne's face. It was with her as the pearl-stringer had said of herself: she "did not know--she could only feel" that the good little woman had something on her conscience, something that she was obliged to hide.

Clo had by this time succeeded in clearing her mind from cobwebs.

Suddenly a light shone like flame upon the mystery. "Peterson!" was the name that printed itself upon the girl's brain. "If he could have got into the flat, he could have stolen both the pearls and papers. Does Miss Blackburne know something, and if she does, why won't she tell?"

It occurred to Clo that, if she could have a few words with Miss Blackburne alone, perhaps the puzzle might be solved.

"Angel," she said, "if there's been a thief in this house, perhaps he's here still. With two manservants, you ought----"

Beverley waited for no more. Any straw was worth catching at. She couldn't wait to ring for Johnson. She rushed out of the boudoir, hoping to find the butler in the dining room. He was there. And while she explained that something had been stolen, that the flat must be searched, Clo got the chance she had wanted.

"Miss Blackburne, you're my friend!" she exclaimed. "This means life or death to me. I'm responsible for that envelope we've lost. Do, for the love of heaven, tell me what happened in this room while Mrs. Sands went out and left you here alone."

The pearl-stringer remained silent. She met Clo's great, imploring eyes without shrinking, but the girl saw that she breathed hard.

"If you don't want me to die, tell me!" Clo implored.

"My child, I would tell you, if I could," she stiffened herself. "But, you see," she finished, "there's nothing to tell. So, I can't."

THE BROWN TRUNK

Clo realized that there was no more to be said, since to accuse Miss Blackburne of lying would make matters worse. When Beverley came back, to say that the servants had been questioned, and the flat searched in vain, the girl had made up her mind what to do next. There were two things, one of which had better be done at once; the second, which must be done before ten o'clock. The first was to settle with Miss Blackburne; and get rid of her. The second thing was to keep the appointment with Peterson. It was more important, Clo thought, to see him than to see O'Reilly, though she expected Angel to suggest an immediate talk with O'Reilly in person or by telephone. She hoped to bring Beverley to her point of view.

"Of course, I rely on you to let me clear myself if you don't find your pearls the way you hope," Miss Blackburne reminded Beverley. "I'm sure you'll let me know when you have news. Meanwhile, there's nothing to stay for, is there? I might as well be with mother."

It was arranged that she should go home in a taxi, to save the time which must be wasted, waiting for Beverley's car. Mrs. Sands paid, of course, and gave the pearl-stringer a present of fifty dollars, "to make up for her trouble."

It was not late, as time goes, but on this night of stress and ordeal, nine-fifteen was a terrible hour. The instant Miss Blackburne was out of the house, the two girls turned to each other, and clasped hands.

"Thank G.o.d, she's gone!" Beverley breathed. "Now I'll call up Justin O'Reilly, and----"

"Wait till I tell you something I've thought of, then you can decide,"

Clo cut in. "I believe that horrible creature, Peterson, may be the thief, not O'Reilly. How he could have got into the flat, and out again, I can't see. But he probably specializes in stunts like that! He has the face--and the fingers--for it. I shouldn't wonder if he terrorized poor Blacky. She's not cut out for a heroine, is she? Maybe the man was under the table in the boudoir. Maybe he warned her that, if she gave him away afterward, he'd do for her and all her belongings. That would scare Blacky blue! She worships her mother. I haven't got the tangle straightened out in my head yet. But this new idea looks good to me, so far. If Peterson's the thief--if he's pocketed the papers and the pearls--it seems to me he'll try and make a quick get-away. Let us jump on him now, at the Hotel Westmorland, before he expects us, and before bothering with O'Reilly. These pearls must be well known. Peterson can't get rid of them, even to a fence, for any big sum. I think he'd exchange, for money, and less important jewels that he might dare to sell. Haven't you got something that your husband's forgotten--or won't mind if he doesn't see you wear?"

"Yes," Beverley answered. "I have six or seven hundred dollars by me.

There's a diamond m.u.f.f-chain, too, and a tiara that Roger himself thinks too old looking for me. He proposed to have the stones reset--but that's months ago. He has forgotten, I'm sure, for he's given me so many other things since. I could bargain with the chain and tiara--and perhaps a few bracelets and rings."

"Let me take the jewels and money in a bag to the Westmorland. I can leave it at the desk while I do the bargaining. It's best to be on the safe side, if you're a mouse holding up a ferret! Besides, there's a question we've 'most lost sight of in this business, Angel. We're not sure the right papers were in the envelope I took from O'Reilly. They might be something else he valued."

"Why, yes!" cried Beverley. "For a moment I counted on their being the right ones--the ones I must give Peterson----"

"Well, I've only to see him to make sure," Clo went on. "He may lie, but I know I can tell by his face. Angel, waste no time on O'Reilly. There's not one second to lose! Get your jewels together, and I'll go."

"We'll both go," said Beverley. "Don't object; it's useless! I won't have you go alone. You've done more than enough already. I'm a wretch to let you slave for me, your first day out of bed! But I daren't call at Peterson's alone, not because I'm afraid for myself, but because of Roger. Besides, I can depend on you to keep your head."

"Very well," Clo consented. "The first thing that occurs to me is this: we must put on plain coats and hats. My new hat I left at the Dietz: I had to! But you'll lend me something. And we'll not 'phone for a taxi.

Best slip away and not let the servants know we've gone. If you've a latch-key, we may go and even get back without a soul being the wiser."

"Come to my room and choose wraps for us both, while I collect the money and what jewels I dare spare," Beverley said. As she spoke, she ran in front of Clo, and opened a safe in the wall not unlike the hiding place Clo had rifled at the Dietz.

The girl selected two automobile coats, one of gray silk, the other of brown, both intended to match the colours of dresses, but inconspicuous and plain. There were toques made of the same material, with thin veils attached. Clo took for herself the brown coat, which was shorter than the gray, and pulled the brown toque well over her red hair. By this time Beverley had stuffed a roll of greenbacks, a chain of platinum set with brilliants, half a dozen sparkling rings and bracelets, and a flexible diamond tiara, into a dark leather handbag. Clo helped her into the long gray coat which covered her evening dress; and the two stole out of the flat like flitting shadows. They went down in the elevator, but the hall-porter was off duty for the night, having left a young understudy in charge.

The girls walked fast to the nearest taxi stand, Clo trying not to breathe hard and so remind Angel of her weakness. As the chauffeur slowed down in front of the Westmorland, Beverley held up her wrist watch for Clo to see.

"Twenty-five minutes to ten," Clo a.s.sured her confidently. "I only hope he won't have gone out. Now, you wait for me in the taxi, Angel, while I----"

"No, you're to wait for me," Beverley decided. "I can do more with the man than you, because there are things you don't know. But don't wait here. It's too far away. I might need you in a hurry. We'll keep the taxi, so there'll be no delay in getting off, and we'll both go into the hotel together. You came this afternoon, so you had better ask for Peterson. We can make up our minds what to do next when we get the answer."

A moment later a tall young woman in a gray motor cloak, and a small young woman in a brown cloak, entered the hotel. The veils that covered their close-fitting toques and fell over their faces were not thick, yet in the electric light the gauze took on a disguising glitter. The pair in their plain wraps, were not conspicuous figures even in a third-rate hotel like the Westmorland, and the clerk whom they approached was not moved to curiosity.

"Mr. Peterson? He's in; came in over an hour ago, and mentioned that he expected a caller; party to go right up."

"He's expecting us, one or both," Clo cut in hastily. "What's his number?"

"658, top floor," said the clerk. "The elevator's just over there to the left--see?"

"We'll go up together," Clo whispered, "and then, if you really think best to see the man alone, I'll hang about somewhere in the hall till you come out and call me."

Beverley made no reply. Already she was fathoms deep in thought. The musty-smelling lift shot them up to the top floor; Beverley, stepping out ahead of Clo, had the air of having forgotten her existence. The girl's anxiety deepened. The best she could do was to guide her friend through dimly lighted, dark-walled corridors, to the right number, 658.

Beverley had, before they left the taxi, given the money and jewels into her companion's hand. Clo's over-strained nerves began to take their revenge. This shabby hotel was an evil place. To her it seemed that each closed door hid something secret and sinister. They met no one between the elevator and Peterson's room. Involuntarily, the two paused an instant in front of number 658 before knocking. No sound came from within. If Peterson were in his room, apparently he was alone. Beverley tapped--a sharp, nervous tap.

"Come in!" cried a voice which sounded far off, as if the speaker called from the furthest corner of the room, or from the depths of a wall cupboard.

"Keep near, but not too near," whispered Beverley, and opened the door.

To her surprise and Clo's there was no light in the room; yet it was not really dark. The blind on the curtainless window opposite the door was rolled up to the top, and let in light from the brilliantly illuminated street six storeys below. As Beverley pa.s.sed in, Clo caught a glimpse of a man's figure comfortably seated in a high-backed armchair in front of the window. She even recognized the mean profile of Peterson, outlined in black against the luminous square of a window pane, and anger p.r.i.c.ked her that he should dare receive Mrs. Sands without rising. Then the door shut, and Clo, obeying the order to "keep near, but not too near," took a few steps down the corridor. Within sight of the door, but not within hearing of voices on the other side unless they should rise to a shout, she hovered uneasily.

It was hateful to Clo that Angel should be alone with the ferret-faced man behind the closed door. He might choke Beverley to death with those sly, thievish hands of his, and the sentinel outside would not know.
