"Well," said Mrs. Sharpe, "not all my tips have had a margin of a length-and-a-half on the right side. But I don't deny that I am very glad to see the percentage. It was very kind of the boy."

"Should we keep as much as ten per cent?" Marion asked doubtfully.

"That was the arrangement," Mrs. Sharpe said equably. "If it hadn't been for me he would be short by the amount of a bet on Bali Boogie at this moment. What is a Bali Boogie, by the way?"

"I am glad you came," Marion said, ignoring her mother's quest for education, "because something unexpected has happened. My watch has come back."

"You mean you've found it?"

"No, oh, no. She sent it back through the post. Look!"

She produced a small, very dirty, white cardboard box, which contained her watch with the blue enamel face and the wrapping that had been round the watch. The wrapping was a square of pinkish tissue paper with a circular stamp reading SUN VALLEY, TRANSVAAL, and had evidently started life embracing an orange. On a torn piece of paper was printed: I DON'T WANT NONE OF IT. The capital I was dotted like a small letter, after the fashion of illiterates.

"Why do you think she turned squeamish about it?" Marion wondered.

"I don't for a moment think she did," Robert said. "I couldn't imagine that girl ever relinquishing anything that her hand had closed over."

"But she did. She sent it back."

"No. Someone sent it back. Someone who was frightened. Someone with a rudimentary conscience, too. If Rose Glyn had wanted to be rid of it she would have thrown it into a pond, without a second thought. But X wants to be rid of it and to make restitution at the same time. X has both a bad conscience and a frightened soul. Now who would have a bad conscience about you just now? Gladys Rees?"

"Yes, of course you are right about Rose. I should have thought of that. She never would have sent it back. She would have put her heel on it sooner. You think perhaps she gave it to Gladys Rees?"

"That might explain a lot. It might explain how Rose got her to court to back up that 'screaming' story. I mean, if she had been the receiver of stolen goods. When you come to think of it, Rose could have very little chance of wearing a watch that the Staples people must quite often have seen on your wrist. It is much more likely that she was 'large' with it in favour of her friend. 'A little thing I picked up. Where does the Rees girl belong to?"

"I don't know where she belongs to; somewhere the other side of the county, I think. But she has come to work for that isolated farm beyond Staples."

"Long ago?"

"I don't know. I don't think so."

"So she could wear a new watch without question. Yes, I think it was Gladys who sent back your watch. If ever there was an unwilling witness it was Gladys on Monday. And if Gladys is shakeable to the point of sending back your property, a faint hope begins to dawn."

"But she has committed perjury," Mrs. Sharpe said. "Even a moron like Gladys Rees must have some glimmering of awareness that that is not well seen in a British court."

"She could plead that she was blackmailed into it. If someone suggested that course to her."

Mrs. Sharpe eyed him. "Isn't there anything in English law about tampering with a witness?" she asked.

"Plenty. But I don't propose to do any tampering."

"What do you propose to do?"

"I must think it over. It is a delicate situation."

"Mr. Blair, the intricacies of the Law have always been beyond me, and are always likely to be, but you won't get yourself put away for contempt of court, or something like that, will you? I can't imagine what the present situation would be like without your support."

Robert said that he had no intention of getting himself put away for anything. That he was a blameless solicitor of unblemished reputation and high moral principles and that she need have no fear either for herself or for him.

"If we could knock the prop of Gladys Rees from under Rose's story it would undermine their whole case," he said. "It's their most valuable piece of evidence: that Rose had mentioned the screaming before there was any suggestion of a charge against you. I suppose you couldn't see Grant's face when Rose was giving evidence? A fastidious mind must be a great handicap in the C.I.D. It must be sad to have your whole case depend on someone you would hate to touch with a barge-pole. Now I must be getting back. May I take the little cardboard box and the scrap of paper with the printing?"

"It was clever of you to have seen that Rose would not have sent it back," Marion said, putting the scrap of paper into the box and giving it to him. "You should have been a detective."

"Either that or a fortune-teller. Everything deduced from the egg-stain on the waistcoat. Au revoir."

Robert drove back to Milford with his mind full of this new possibility. It was no solution to their predicament, but it might be a lifeline.

In the office he found Mr. Ramsden waiting for him; long, grey, lean, and dour.

"I came to see you, Mr. Blair, because it wasn't a thing that could be said over the telephone very well."

"Well?"

"Mr. Blair, we're wasting your money. Do you happen to know what the white population of the world is?"

"No, I don't."

"Neither do I. But what you're asking me to do is to pick this girl out of the white population of the world. Five thousand men working for a year mightn't do it. One man might do it tomorrow. It's a matter of pure chance."

"But it always has been that."

"No. In the first days the chances were fair. We covered the obvious places. The ports, the airports, the travel places, the best known 'honeymoon' places. And I didn't waste your time or money in any travelling. I have contacts in all the big towns and in a lot of the smaller ones, and I just send them a request saying: 'Find out if such and such a person stayed at one of your hotels, and the answer is back in a few hours. Answers from all over Britain. Well, that done, we are left with a small proposition called the rest of the world. And I don't like wasting your money, Mr. Blair. Because that is what it will amount to."

"Do I understand that you are giving up?"

"I don't put it like that, exactly."

"You think I should give you notice because you have failed."

Mr. Ramsden stiffened noticeably at the word "failed."

"It's throwing good money away on a long chance. It isn't a business proposition, Mr. Blair. It isn't even a good gamble."

"Well, I have something for your consideration that is definite enough to please you, I think." He fished the little cardboard box out of his pocket. "One of the witnesses on Monday was a girl called Gladys Rees. Her role was to supply evidence that her friend Rose Glyn had talked to her about screams at The Franchise long before the police were interested in the place. Well, she supplied the evidence all right, but not con amore, as you might say. She was nervous, unwilling, and was obviously hating it-in contrast to her friend Rose who was having the time of her life. One of my local colleagues suggested that Rose had got her there by pressure, but that didn't seem very likely at the time. This morning, however, the watch that Rose stole from Miss Sharpe came back by post in this box, with the printed message enclosed. Now Rose would never have bothered to return the watch; she has no conscience at all. Nor would she have written the note; having no desire to repudiate anything. The conclusion is inescapable, that it was Gladys who received the watch-Rose could not have worn it without detection anyhow-and that that was how Rose got her to back up her lies."

He paused to let Ramsden comment. Mr. Ramsden nodded; but it was an interested nod.

"Now we can't approach Gladys with any kind of argument without being accused of intimidating witnesses. I mean, getting her to go back on her story before the Assizes is not possible. All we can do is to concentrate on breaking her down at the Assizes. Kevin Macdermott could probably do it by force of personality and persistent questions, but I doubt it; and anyhow the Court might stop him before he had achieved anything. They are apt to look sideways on him when he begins to ride a witness."
