He ushered them into a room at the back of the house, furnished as a library. The collection of books was a magnificent one, and Tuppence noticed that all one wall was devoted to works on crime and criminology. There were several deep-padded leather arm-chairs, and an old-fashioned open hearth. In the window was a big roll-top desk strewn with papers at which the master of the house was sitting.

He rose as they entered.

"You have a message for me? Ah"-he recognized Tuppence with a smile-"it's you, is it? Brought a message from Mrs. Vandemeyer, I suppose?"

"Not exactly," said Tuppence. "In fact, I'm afraid I only said that to be quite sure of getting in. Oh, by the way, this is Mr. Hersheimmer, Sir James Peel Edgerton."

"Pleased to meet you," said the American, shooting out a hand.

"Won't you both sit down?" asked Sir James. He drew forward two chairs.

"Sir James," said Tuppence, plunging boldly, "I dare say you will think it is most awful cheek of me coming here like this. Because, of course, it's nothing whatever to do with you, and then you're a very important person, and of course Tommy and I are very unimportant." She paused for breath.

"Tommy?" queried Sir James, looking across at the American.

"No, that's Julius," explained Tuppence. "I'm rather nervous, and that makes me tell it badly. What I really want to know is what you meant by what you said to me the other day? Did you mean to warn me against Mrs. Vandemeyer? You did, didn't you?"

"My dear young lady, as far as I recollect I only mentioned that there were equally good situations to be obtained elsewhere."

"Yes, I know. But it was a hint, wasn't it?"

"Well, perhaps it was," admitted Sir James gravely.

"Well, I want to know more. I want to know just WHY you gave me a hint."

Sir James smiled at her earnestness.

"Suppose the lady brings a libel action against me for defamation of character?"

"Of course," said Tuppence. "I know lawyers are always dreadfully careful. But can't we say 'without prejudice' first, and then say just what we want to."

"Well," said Sir James, still smiling, "without prejudice, then, if I had a young sister forced to earn her living, I should not like to see her in Mrs. Vandemeyer's service. I felt it incumbent on me just to give you a hint. It is no place for a young and inexperienced girl. That is all I can tell you."

"I see," said Tuppence thoughtfully. "Thank you very much. But I'm not REALLY inexperienced, you know. I knew perfectly that she was a bad lot when I went there-as a matter of fact that's WHY I went--" She broke off, seeing some bewilderment on the lawyer's face, and went on: "I think perhaps I'd better tell you the whole story, Sir James. I've a sort of feeling that you'd know in a minute if I didn't tell the truth, and so you might as well know all about it from the beginning. What do you think, Julius?"

"As you're bent on it, I'd go right ahead with the facts," replied the American, who had so far sat in silence.

"Yes, tell me all about it," said Sir James. "I want to know who Tommy is."

Thus encouraged Tuppence plunged into her tale, and the lawyer listened with close attention.

"Very interesting," he said, when she finished. "A great deal of what you tell me, child, is already known to me. I've had certain theories of my own about this Jane Finn. You've done extraordinarily well so far, but it's rather too bad of-what do you know him as?-Mr. Carter to pitchfork you two young things into an affair of this kind. By the way, where did Mr. Hersheimmer come in originally? You didn't make that clear?"

Julius answered for himself.

"I'm Jane's first cousin," he explained, returning the lawyer's keen gaze.

"Ah!"

"Oh, Sir James," broke out Tuppence, "what do you think has become of Tommy?"

"H'm." The lawyer rose, and paced slowly up and down. "When you arrived, young lady, I was just packing up my traps. Going to Scotland by the night train for a few days' fishing. But there are different kinds of fishing. I've a good mind to stay, and see if we can't get on the track of that young chap."

"Oh!" Tuppence clasped her hands ecstatically.

"All the same, as I said before, it's too bad of-of Carter to set you two babies on a job like this. Now, don't get offended, Miss-er--"

"Cowley. Prudence Cowley. But my friends call me Tuppence."

"Well, Miss Tuppence, then, as I'm certainly going to be a friend. Don't be offended because I think you're young. Youth is a failing only too easily outgrown. Now, about this young Tommy of yours--"

"Yes." Tuppence clasped her hands.

"Frankly, things look bad for him. He's been butting in somewhere where he wasn't wanted. Not a doubt of it. But don't give up hope."

"And you really will help us? There, Julius! He didn't want me to come," she added by way of explanation.

"H'm," said the lawyer, favouring Julius with another keen glance. "And why was that?"

"I reckoned it would be no good worrying you with a petty little business like this."

"I see." He paused a moment. "This petty little business, as you call it, bears directly on a very big business, bigger perhaps than either you or Miss Tuppence know. If this boy is alive, he may have very valuable information to give us. Therefore, we must find him."

"Yes, but how?" cried Tuppence. "I've tried to think of everything."

Sir James smiled.

"And yet there's one person quite near at hand who in all probability knows where he is, or at all events where he is likely to be."

"Who is that?" asked Tuppence, puzzled.

"Mrs. Vandemeyer."

"Yes, but she'd never tell us."

"Ah, that is where I come in. I think it quite likely that I shall be able to make Mrs. Vandemeyer tell me what I want to know."

"How?" demanded Tuppence, opening her eyes very wide.

"Oh, just by asking her questions," replied Sir James easily. "That's the way we do it, you know."

He tapped with his finger on the table, and Tuppence felt again the intense power that radiated from the man.

"And if she won't tell?" asked Julius suddenly.

"I think she will. I have one or two powerful levers. Still, in that unlikely event, there is always the possibility of bribery."

"Sure. And that's where I come in!" cried Julius, bringing his fist down on the table with a bang. "You can count on me, if necessary, for one million dollars. Yes, sir, one million dollars!"

Sir James sat down and subjected Julius to a long scrutiny.

"Mr. Hersheimmer," he said at last, "that is a very large sum."

"I guess it'll have to be. These aren't the kind of folk to offer sixpence to."

"At the present rate of exchange it amounts to considerably over two hundred and fifty thousand pounds."

"That's so. Maybe you think I'm talking through my hat, but I can deliver the goods all right, with enough over to spare for your fee."

Sir James flushed slightly.

"There is no question of a fee, Mr. Hersheimmer. I am not a private detective."

"Sorry. I guess I was just a mite hasty, but I've been feeling bad about this money question. I wanted to offer a big reward for news of Jane some days ago, but your crusted institution of Scotland Yard advised me against it. Said it was undesirable."

"They were probably right," said Sir James dryly.

"But it's all O.K. about Julius," put in Tuppence. "He's not pulling your leg. He's got simply pots of money."

"The old man piled it up in style," explained Julius. "Now, let's get down to it. What's your idea?"

Sir James considered for a moment or two.

"There is no time to be lost. The sooner we strike the better." He turned to Tuppence. "Is Mrs. Vandemeyer dining out to-night, do you know?"

"Yes, I think so, but she will not be out late. Otherwise, she would have taken the latchkey."
