“The evidence of Mr. Hardman, who is a member of a New York detective agency–” (Several heads turned, to look at Mr. Hardman.) – “shows that no one could have passed his compartment (No. 16 at the extreme end) without being seen by him. We are therefore forced to the conclusion that the murderer is to be found among the occupants of one particular coach – the Stamboul-Calais coach.
“That, I will say,
“
“But I will put before you an alternative theory. It is very simple. Mr. Ratchett had a certain enemy whom he feared. He gave Mr. Hardman a description of this enemy and told him that the attempt, if made at all, would most probably be made on the second night out from Stamboul.
“Now I put it to you, ladies and gentlemen, that Mr. Ratchett knew a good deal more than he told. The enemy, as Mr. Ratchett expected, joined the train
“That’s so,” said Mrs. Hubbard, nodding her head.
“He thrust the dagger he had used into Mrs. Hubbard’s sponge-bag in passing. Without knowing it, he lost a button of his uniform. Then he slipped out of the compartment and along the corridor. He hastily thrust the uniform into a suitcase in an empty compartment, and a few minutes later, dressed in ordinary clothes, he left the train just before it started off, using the same means for egress – the door near the dining-car.”
Everybody gasped.
“What about that watch?” demanded Mr. Hardman.
“There you have the explanation of the whole thing.
“But it is absurd, that explanation!” cried M. Bouc. “What of the voice that spoke from the compartment at twenty-three minutes to one? It was either the voice of Ratchett – or else that of his murderer.”
“Not necessarily. It might have been – well – a third person. One who had gone in to speak to Ratchett and found him dead. He rang the bell to summon the conductor; then, as you express it, the wind rose in him – he was afraid of being accused of the crime, and he spoke pretending to be Ratchett.”
“
Poirot looked at Mrs. Hubbard. “Yes, Madame, you were going to say–”
“Well, I don’t quite know what I was going to say. Do you think I forgot to put my watch back too?”
“No, Madame. I think you heard the man pass through – but unconsciously. Later you had a nightmare of a man being in your compartment and woke up with a start and rang for the conductor.”
“Well, I suppose that’s possible,” admitted Mrs. Hubbard.
Princess Dragomiroff was looking at Poirot with a very direct glance. “How do you explain the evidence of my maid, Monsieur?”
“Very simply, Madame. Your maid recognised the handkerchief I showed her as yours. She somewhat clumsily tried to shield you. She did encounter the man, but earlier – while the train was at Vincovci station. She pretended to have seen him at a later hour, with a confused idea of giving you a water-tight alibi.”
The Princess bowed her head. “You have thought of everything, Monsieur. I – I admire you.”
There was a silence.
Then everyone jumped as Dr. Constantine suddenly hit the table a blow with his fist.
“But no,” he said. “No, no, and again no! That is an explanation that will not hold water. It is deficient in a dozen minor points. The crime was not committed so – M. Poirot must know that perfectly well.”
Poirot turned a curious glance on him. “I see,” he said, “that I shall have to give you my second solution. But do not abandon this one too abruptly. You may agree with it later.”
He turned back again to face the others.
“There is another possible solution of the crime. This is how I arrived at it.
