"What shall it be?" the newcomer asked.

"I've just taken dinner," Mr. Coulson said. "Coffee and cognac'll do me all right."

"And a Martini c.o.c.ktail for me," the young man ordered. "I am dining down in the restaurant with some friends later on. Come over to this corner, Mr. Coulson. Why, you're looking first-rate. Great boat, the Lusitania, isn't she? What sort of a trip did you have?"

So they talked till the drinks had been brought and paid for, till another little party had quitted the room and they sat in their lonely corner, secure from observation or from any possibility of eavesdropping. Then Mr. Richard Vanderpole leaned forward in his chair and dropped his voice.

"Coulson," he said, "the chief is anxious. We don't understand this affair. Do you know anything?"

"Not a d----d thing!" Coulson answered.

"Were you shadowed on the boat?" the young man asked.

"Not to my knowledge," Coulson answered. "Fynes was in his stateroom six hours before we started. I can't make head nor tail of it."

"He had the papers, of course?"

"Sewn in the lining of his coat," Coulson muttered. "You read about that in tonight's papers. The lining was torn and the s.p.a.ce empty. He had them all right when he left the steamer."

The young man looked around; the room was still empty.

"I'm fresh in this," he said. "I got some information this afternoon, and the chief sent me over to see you on account of it. We had better not discuss possibilities, I suppose? The thing's too big. The chief's almost off his head. Is there any chance, do you think, Coulson, that this was an ordinary robbery? I am not sure that the special train wasn't a mistake."

"None whatever," Coulson declared.

"How do you know?" his companion asked quickly.

"Well, I've lied to those reporters and chaps," Coulson admitted,--"lied with a purpose, of course, as you people can understand. The money found upon Fynes was every penny he had when he left Liverpool."

The young man set his teeth.

"It's something to know this, at any rate," he declared. "You did right, Coulson, to put up that bluff. Now about the duplicates?"

"They are in my suitcase," Coulson answered, "and according to the way things are going, I shan't be over sorry to get rid of them. Will you take them with you?"

"Why, sure!" Vanderpole answered. "That's what I'm here for."

"You had better wait right here, then," Coulson said, "I'll fetch them."

He made his way up to his room, undid his dressing bag, which was fastened only with an ordinary lock, and from between two shirts drew out a small folded packet, no bigger than an ordinary letter. It was a curious circ.u.mstance that he used only one hand for the search and with the other gripped the b.u.t.t of a small revolver. There was no one around, however, nor was he disturbed in any way. In a few minutes he returned to the bar smoking room, where the young man was still waiting, and handed him the letter.

"Tell me," the latter asked, "have you been shadowed at all?"

"Not that I know of," Coulson answered.

"Men with quick instincts," Vanderpole continued, "can always tell when they are being watched. Have you felt anything of the sort?"

Coulson hesitated for one moment.

"No," he said. "I had a caller whose manner I did not quite understand.

She seemed to have something at the back of her head about me."

"She! Was it a woman?" the young man asked quickly.

Coulson nodded.

"A young lady," he said,--"Miss Penelope Morse, she called herself."

Mr. Richard Vanderpole stood quite still for a moment.

"Ah!" he said softly. "She might have been interested."

"Does the chief want me at all?" Coulson asked.

"No!" Vanderpole answered. "Go about your business as usual. Leave here for Paris, say, in ten days. There will probably be a letter for you at the Grand Hotel by that time."

They walked together toward the main exit. The young man's face had lost some of its grimness. Once more his features wore that look of pleasant and genial good-fellowship which seems characteristic of his race after business hours.

"Say, Mr. Coulson," he declared, as they pa.s.sed across the hall, "you and I must have a night together. This isn't New York, by any manner of means, or Paris, but there's some fun to be had here, in a quiet way.

I'll phone you tomorrow or the day after."

"Sure!" Mr. Coulson declared. "I'd like it above all things."

"I must find a taxicab," the young man remarked. "I've a busy hour before me. I've got to go down and see the chief, who is dining somewhere in Kensington, and get back again to dine here at half past seven in the restaurant."

"I guess you'll have to look sharp, then." Mr. Coulson remarked. "Do you see the time?"

Vanderpole glanced at the clock and whistled softly to himself.

"Tell you what!" he exclaimed, "I'll write a note to one of the friends I've got to meet, and leave it here. Boy," he added, turning to a page boy, "get me a taxi as quick as you can."

The boy ran out into the Strand, and Vanderpole, sitting down at the table, wrote a few lines, which he sealed and addressed and handed to one of the reception clerks. Then he shook hands with Coulson and threw himself into a corner of the cab which was waiting.

"Drive down the Brompton Road," he said to the man. "I'll direct you later."

It was a quarter past seven when he left the hotel. At half past a policeman held up his hand and stopped the taxi, to the driver's great astonishment, as he was driving slowly across Melbourne Square, Kensington.

"What's the matter?" the man asked. "You can't say I was exceeding my speed limit."

The policeman scarcely noticed him. His head was already through the cab window.

"Where did you take your fare up?" he asked quickly.

"Savoy Hotel," the man answered. "What's wrong with him?"

The policeman opened the door of the cab and stepped in.

"Never you mind about that," he said. "Drive to the South Kensington police station as quick as you can."
