‘His valet, Masterman, will have to know.’
‘He probably knows already,’ said Poirot dryly. ‘If so try to get him to hold his tongue.’
‘That oughtn’t to be difficult. He’s a Britisher, and does what he calls “Keeps himself to himself.” He’s a low opinion of Americans and no opinion at all of any other nationality.’
‘Thank you, M. MacQueen.’
The American left the carriage.
‘Well?’ demanded M. Bouc. ‘You believe what he says, this young man?’
‘He seems honest and straightforward. He did not pretend to any affection for his employer as he probably would have done had he been involved in any way. It is true M. Ratchett did not tell him that he had tried to enlist my services and failed, but I do not think that is really a suspicious circumstance. I fancy M. Ratchett was a gentleman who kept his own counsel on every possible occasion.’
‘So you pronounce one person at least innocent of the crime,’ said M. Bouc jovially.
Poirot cast on him a look of reproach.
‘Me, I suspect everybody till the last minute,’ he said. ‘All the same, I must admit that I cannot see this sober, long-headed MacQueen losing his head and stabbing his victim twelve or fourteen times. It is not in accord with his psychology—not at all.’
‘No,’ said Mr Bouc thoughtfully. ‘That is the act of a man driven almost crazy with a frenzied hate—it suggests more the Latin temperament. Or else it suggests, as our friend the chef de train insisted, a woman.’
Followed by Dr Constantine, Poirot made his way to the next coach and the compartment occupied by the murdered man. The conductor came and unlocked the door for them with his key.
The two men passed inside. Poirot turned inquiringly to his companion.
‘How much has been disarranged in this compartment?’
‘Nothing has been touched. I was careful not to move the body in making my examination.’
Poirot nodded. He looked round him.
The first thing that struck the senses was the intense cold. The window was pushed down as far as it would go and the blind was drawn up.
‘Brrr,’ observed Poirot.
The other smiled appreciatively.
‘I did not like to close it,’ he said.
Poirot examined the window carefully.
‘You are right,’ he announced. ‘Nobody left the carriage this way. Possibly the open window was intended to suggest the fact, but, if so, the snow has defeated the murderer’s object.’
He examined the frame of the window carefully. Taking a small case from his pocket he blew a little powder over it.
‘No fingerprints at all,’ he said. ‘That means it has been wiped. Well, if there had been fingerprints it would have told us very little. They would have been those of M. Ratchett or his valet or the conductor. Criminals do not make mistakes of that kind nowadays.
‘And that being so,’ he added cheerfully, ‘we might as well shut the window. Positively it is the cold storage in here!’
He suited the action to the word and then turned his attention for the first time to the motionless figure lying in the bunk.
Ratchett lay on his back. His pyjama jacket, stained with rusty patches, had been unbuttoned and thrown back.
‘I had to see the nature of the wounds, you see,’ explained the doctor.
Poirot nodded. He bent over the body. Finally he straightened himself with a slight grimace.
‘It is not pretty,’ he said. ‘Someone must have stood there and stabbed him again and again. How many wounds are there exactly?’
‘I make it twelve. One or two are so slight as to be practically scratches. On the other hand, at least three would be capable of causing death.’
Something in the doctor’s tone caught Poirot’s attention. He looked at him sharply. The little Greek was standing staring down at the body with a puzzled frown.
‘Something strikes you as odd, does it not?’ he asked gently. ‘Speak, my friend. There is something here that puzzles you?’
‘You are right,’ acknowledged the other.
‘What is it?’
‘You see, these two wounds—here and here,’—he pointed. ‘They are deep, each cut must have severed blood-vessels—and yet—the edges do not gape. They have not bled as one would have expected.’
‘Which suggests?’
‘That the man was already dead—some little time dead—when they were delivered. But that is surely absurd.’
‘It would seem so,’ said Poirot thoughtfully. ‘Unless our murderer figured to himself that he had not accomplished his job properly and came back to make quite sure; but that is manifestly absurd! Anything else?’
‘Well, just one thing.’
‘And that?’
‘You see this wound here—under the right arm—near the right shoulder. Take this pencil of mine. Could you deliver such a blow?’
Poirot raised his hand.
‘Précisément,’ he said. ‘I see. With the right hand it is exceedingly difficult—almost impossible. One would have to strike backhanded, as it were. But if the blow were struck with the left hand—’
‘Exactly, M. Poirot. That blow was almost certainly struck with the left hand.’
‘So that our murderer is left-handed? No, it is more difficult than that, is it not?’
‘As you say, M. Poirot. Some of these other blows are just as obviously right-handed.’
‘Two people. We are back at two people again,’ murmured the detective. He asked abruptly:
‘Was the electric light on?’
‘It is difficult to say. You see it is turned off by the conductor every morning about ten o’clock.’
‘The switches will tell us,’ said Poirot.
He examined the switch of the top light and also the roll back bed-head light. The former was turned off. The latter was closed.
‘Eh bien,’ he said thoughtfully. ‘We have here a hypothesis of the First and Second Murderer, as the great Shakespeare would put it. The First Murderer stabbed his victim and left the compartment, turning off the light. The Second Murderer came in the dark, did not see that his or her work had been done and stabbed at least twice at a dead body. Que pensez vous de ça?’
‘Magnificent,’ said the little doctor with enthusiasm.
The other’s eyes twinkled.
‘You think so? I am glad. It sounded to me a little like the nonsense.’
‘What other explanation can there be?’
‘That is just what I am asking myself. Have we here a coincidence or what? Are there any other inconsistencies, such as would point to two people being concerned?’
‘I think I can say yes. Some of these blows, as I have already said, point to a weakness—a lack of strength or
