“Not such a famous alibi,” said Poirot. “The hands of the watch pointed to 1.15 – the exact time when the intruder actually left the scene of the crime.”

“True,” said M. Bouc, a little confused. “What then does the watch convey to you?”

“If the hands were altered – I say if – then the time at which they were set must have a significance. The natural reaction would be to suspect anyone who had a reliable alibi for the time indicated – in this case, 1.15.”

“Yes, yes,” said the doctor. “That reasoning is good.”

“We must also pay a little attention to the time the intruder entered the compartment. When had he an opportunity of doing so? Unless we are to assume the complicity of the real conductor, there was only one time when he could have done so – during the time the train stopped at Vincovci. After the train left Vincovci the conductor was sitting facing the corridor, and whereas any one of the passengers would pay little attention to a Wagon Lit attendant, the one person who would notice an impostor is the real conductor. But during the halt at Vincovci the conductor is out on the platform. The coast is clear.”

“And by our former reasoning, it must be one of the passengers,” said M. Bouc. “We come back to where we were. Which of them?”

Poirot smiled.

“I have made a list,” he said. “If you like to see it, it will perhaps refresh your memory.”

The doctor and M. Bouc pored over the list together. It was written out neatly in a methodical manner in the order in which the passengers had been interviewed.

HECTOR MACQUEEN, American subject, Berth No. 6, Second Class.

Motive – Possibly arising out of association with dead man?

Alibi – From midnight to 2 A.M. (Midnight to 1.30 vouched for by Col. Arbuthnot, and 1. 15 to 2 vouched for by conductor.)

Evidence against him – None.

Suspicious circumstances – None.

CONDUCTOR PIERRE MICHEL, French subject.

Motive – None.

Suspicious circumstances – The Wagon Lit uniform found is a point in his favor since it seems to have been intended to throw suspicion on him.

NOTE: – The evidence of the passengers is supported by the statement of the conductor that no one entered or left Mr. Ratchett’s compartment from midnight to 1 o’clock (when he himself went into the next coach) and from 1.15 to 2 o’clock.

“That document, you understand,” said Poirot, “is a mere precis of the evidence we heard, arranged in that way for convenience.”

With a grimace, M. Bouc handed it back. “It is not illuminating,” he said.

“Perhaps you may find this more to your taste,” said Poirot, with a slight smile as he handed him a second sheet of paper.

On the paper was written:

THINGS NEEDING EXPLANATION

The handkerchief marked with the initial H. Whose is it?

The pipe-cleaner. Was it dropped by Colonel Arbuthnot? Or by someone else?

Who wore the scarlet kimono?

Who was the man or woman masquerading in Wagon Lit uniform?

Why do the hands of the watch point to 1.15?

Was the murder committed at that time?

Was it earlier?

Was it later?

Can we be sure that Ratchett was stabbed by more than one person?

What other explanation of his wounds can there be?

“Well, let us see what we can do,” said M. Bouc, brightening a little at this challenge to his wits. The handkerchief, to begin with. Let us by all means be orderly and methodical.”

“Assuredly,” said Poirot, nodding his head in a satisfied fashion.

M. Bouc continued somewhat didactically.

The initial H is connected with three people – Mrs. Hubbard, Miss Debenham, whose second name is Hermione, and the maid Hildegarde Schmidt.”

“Ah! And of those three?”

“It is difficult to say. But I think I should vote for Miss Debenham. For all one knows she may be called by her second name and not her first. Also there is already some suspicion attaching to her. That conversation you overheard, mon cher, was certainly a little curious, and so is her refusal to explain it.”

“As for me, I plump for the American,” said Dr. Constantine. “It is a very expensive handkerchief, that; and Americans, as all the world knows, do not care what they pay.”
