"Business."

"Do you always travel first-class, Mr. Hardman?"

"You are Cyrus Bethman Hardman, United States subject, forty-one years of age, travelling salesman for typewriting ribbons?"

"You are travelling from Stamboul to Paris?"

Poirot consulted the passport lying in front of him.

"That's all right by me. Guess that's the only way to tackle the job."

"We are of necessity interviewing all the passengers on the train."

"Yes, sir. The firm pays my travelling expenses." He winked.

"O. K., that's me."

"Sure." He shifted the chewing gum deftly.

"That's so."

He wore a somewhat loud check suit, a pink shirt, a flashy tiepin, and was rolling something round his tongue as he entered the dining car. He had a big, fleshy, coarse-featured face, with a good humoured expression.

"Reason?"

"Morning, gentlemen," he said. "What can I do for you?"

"You have heard of this murder, Mr.-- er -- Hardman?"

The last of the first-class passengers to be interviewed -- Mr. Hardman -- was the big flamboyant American who had shared a table with the Italian and the valet.

"Now, Mr. Hardman, we come to the events of last night."

"Exactly nothing at all."

"Ah, that is a pity. Perhaps, Mr. Hardman, you will tell us exactly what you did last night, from dinner onwards?"

"What can you tell us about the matter?"

For the first time the American did not seem ready with his reply. At last he said: "Excuse me, gentlemen, but just who are you? Put me wise."

"I've heard of you," said Mr. Hardman. He reflected a minute or two longer. "Guess I'd better come clean."

"And you yourself?"

The American nodded.

"It will certainly be advisable for you to tell us all you know," said Poirot dryly.

"I am Hercule Poirot. I am engaged by the company to investigate this matter."

"This is M. Bouc, a director of the Compagnie des Wagons Lits. This gentleman is the doctor who examined the body."

"Please explain, Mr. Hardman."

"You'd have said a mouthful if there was anything I did know. But I don't. I know nothing at all -- just as I said. But I ought to know something. That's what makes me sore. I ought to."

Mr. Hardman sighed, removed the chewing gum, and dived into a pocket. At the same time his whole personality seemed to undergo a change. He became less of a stage character and more of a real person. The resonant nasal tones of his voice became modified.

Mr. CYRUS B. HARDMAN

McNeil's Detective Agency,

"Sure. Things came about this way. I'd come over to Europe trailing a couple of crooks -- nothing to do with this business. The chase ended in Stamboul. I wired the Chief and got his instructions to return, and I would have been making my tracks back to little old New York when I got this."

NEW YORK.

Dear Sir,-- You have been pointed out to me as an operative of the McNeil Detective Agency. Kindly report to my suite at four o'clock this afternoon.

He pushed across a letter.

Poirot scrutinized the card flipped across to him. M. Bouc peered over his shoulder.

"Now, Mr. Hardman," he said. "Let us hear the meaning of this."

The heading at the top was the Tokatlian Hotel.

"That passport's a bit of bluff," he said. "That's who I really am."

Poirot knew the name. It was one of the best known and most reputable private detective agencies in New York.

"Eh bien?"

"I reported at the time stated and Mr. Ratchett put me wise to the situation. He showed me a couple of letters he'd got."

"Did he give you any indication of the line you were to take?"

It was signed 'S. E. Ratchett."

"He was alarmed?"

"Sure. He had it all taped out. It was his idea that I should travel in the compartment alongside his -- well, that was blown upon straight away. The only place I could get was berth No. 16, and I had a bit of a job getting that. I guess the conductor likes to keep that compartment up his sleeve. But that's neither here nor there. When I looked all round the situation, it seemed to me that No. 16 was a pretty good strategic position. There was only the dining car in front of the Stamboul sleeping car, the door on to the platform at the front end was barred at night. The only way a thug could come was through the rear end door to the platform or along the train from the rear -- in either case he'd have to pass right by my compartment."

"Pretended not to be, but he was rattled all right. He put up a proposition to me. I was to travel by the same train as he did to Parrus and see that nobody got him. Well, gentlemen, I did travel by the same train and, in spite of me, somebody did get him. I certainly feel sore about it. It doesn't look any too good for me."

"Well, I knew what he looked like. Mr. Ratchett described him to me."

"Ratchett was Cassetti, the Armstrong murderer."

"Which, mister?"

"No, he was kinder reticent about that part of it. Just said the fellow was out for his blood and meant to get it."

Mr. Hardman gave way to a prolonged whistle.

"He certainly knew more than he told his secretary," said Poirot thoughtfully. "Did he tell you anything about this enemy of his? Did he, for instance, say why his life was threatened?"

"I don't get you."

"Ratchett. You recognized him?"

Hardman went on: "A small man, dark, with a womanish kind of voice -- that's what the old man said. Said, too, that he didn't think it would be the first night out. More likely the second or third."

"A small man -- dark -- with a womanish voice," said Poirot thoughtfully. Then, fixing a sharp glance on Hardman, he said: "You knew who he really was, of course?"

All three men leaned forward eagerly.

"He knew something," said M. Bouc.

"What?"

"You had no idea, I suppose, of the identity of the possible assailant."

"Do you know of anyone connected with the Armstrong case who answers to that description -- small, dark, womanish voice?"

Hardman reflected a minute or two. "It's hard to say. Pretty nearly everyone to do with that case is dead."

"That certainly is some surprise!" he said. "Yes, sir! No, I didn't recognize him. I was away out West when that case came on. I suppose I saw photos of him in the papers, but I wouldn't recognize my own mother when a press photographer had done with her. Well, I don't doubt that a few people had it in for Cassetti all right."

"Ah, but we have reason to believe that this crime is connected with the Armstrong case."

"There was the girl who threw herself out of the window, remember."

"Sure. That's a good point, that. She was a foreigner of some kind. Maybe she had some wop relations. But you've got to remember that there were other cases besides the Armstrong case. Cassetti had been running this kidnapping stunt some time. You can't concentrate on that only."

Mr. Hardman cocked an inquiring eye. Poirot did not respond. The American shook his head.

"I can't call to mind anybody answering that description in the Armstrong case," he said slowly. "But of course I wasn't in it and didn't know much about it."

"Well, continue your narrative, M. Hardman."

"You are sure of that, M. Hardman?"

"Sure. He sits on that little seat almost flush with my door."

"I'm plumb certain. Nobody got on that train from outside and nobody came along the train from the rear carriages. I'll take my oath on that."

"There's very little to tell. I got my sleep in the daytime and stayed awake on the watch at night. Nothing suspicious happened the first night. Last night was the same, as far as I was concerned. I had my door a little ajar and watched. No stranger passed."

"Did he leave that seat at all after the train stopped at Vincovci?"

"That was the last station? Why, yes, he answered a couple of bells -- that would be just after the train came to a halt for good. Then, after that, he went past me into the rear coach -- was there about a quarter of an hour. There was a bell ringing like mad and he came back running. I stepped out into the corridor to see what it was all about -- felt a mite nervous, you understand -- but it was only the American dame. She was raising hell about something or other. I grinned. Then he went on to another compartment and came back and got a bottle of mineral water for someone. After that he settled down in his seat till he went up to the far end to make somebody's bed up. I don't think he stirred after that until about five o'clock this morning."

"Could you see the conductor from your position?"

"Not me." He helped himself, then strode briskly off.

"There is no one, I suppose, who can confirm your story of your identity, M. Hardman?"

"A small man, dark, with a high-pitched voice," said M. Bouc thoughtfully.

The other complied.

"On this train? Well, not exactly. Unless it might be young MacQueen. I know him well enough -- seen him in his father's office in New York -- but that's not to say he'll remember me from a crowd of other operatives. No, Mr. Poirot, you'll have to wait and cable New York when the snow lets up. But it's O. K. I'm not telling the tale. Well, so long, gentlemen. Pleased to have met you, Mr. Poirot."

"That I can't say. He may have done."

Poirot nodded. Automatically his hands straightened the papers on the table. He picked up the official card once more.

"He has given us a piece of very interesting evidence," said M. Bouc.

The three men looked at each other.

"A description which applies to no one on the train," said Poirot.

"Yes, yes. I know the type. Besides, it is a story that would be very easily disproved."

"You think he is genuine?" asked Dr. Constantine.

Poirot proffered his cigarette case. "But perhaps you prefer a pipe?"

"Be so good as just to initial this," he said.

"Yes, indeed."

"Did he doze off at all?"
