bottom of this case. There is some deep mystery here. But who is the victim this time?'
'That is just what nobody can tell us, monsieur. He has not been identified.'
'Where is the body?' asked the doctor.
Giraud moved aside a little. 'There in the corner. He has been stabbed to the heart, as you see. And with the dagger that was stolen yesterday morning. I fancy that the murder followed hard upon the theft-but that is for you to say. You can handle the dagger freely-there are no fingerprints on it.'
The doctor knelt down by the dead man and Giraud turned to the examining magistrate.
'A pretty little problem, is it not? But I shall solve it.'
'And so no one can identify him,' mused the magistrate. 'Could it possibly be one of the assassins? They may have fallen out among themselves.'
Giraud shook his head. 'The man is a Frenchman. I would take my oath on that.'
But at that moment they were interrupted by the doctor, who was sitting back on his heels with a perplexed expression.
'You say he was killed yesterday morning?'
'I fix it by the theft of the dagger,' explained Giraud. 'He may, of course, have been killed later in the day.'
'Later in the day? Fiddlesticks! This man has been dead at least forty-eight hours, and probably longer.'
We stared at each other in blank amazement.
Chapter 15. A Photograph
The doctor's words were so surprising that we were all momentarily taken aback. Here was a man stabbed with a dagger which we knew to have been stolen only twenty-four hours previously, and yet Dr. Durand asserted positively that he had been dead at least forty-eight hours! The whole thing was fantastic to the last extreme.
We were still recovering from the surprise of the doctor's announcement when a telegram was brought to me. It had been sent up from the hotel to the villa. I tore it open. It was from Poirot, and announced his return by the train arriving at Merlinville at 12.28.
I looked at my watch and saw that I had just time to get comfortably to the station and meet him there. I felt that it was of the utmost importance that he should know at once of the new and startling developments in the case.
Evidently, I reflected, Poirot had had no difficulty in finding what he wanted in Paris. The quickness of his return proved that. Very few hours had sufficed. I wondered how he would take the exciting news I had to impart.
The train was some minutes late, and I strolled aimlessly up and down the platform until it occurred to me that I might pass the time by asking a few questions as to who had left Merlinville by the last train on the evening of the tragedy.
I approached the chief porter, an intelligent-looking man, and had little difficulty in persuading him to enter upon the subject. It was a disgrace to the police, he hotly affirmed, that such brigands or assassins should be allowed to go about unpunished. I hinted that there was some possibility they might have left by the midnight train but he negatived the idea decidedly. He would have noticed two foreigners-he was sure of it. Only about twenty people had left by the train, and he could not have failed to observe them.
I do not know what put the idea into my head-possibly it was the deep anxiety underlying Marthe Daubreuil's eyes-but I asked suddenly: 'Young Monsieur Renauld-he did not leave by that train, did he?'
'Ah, no, monsieur. To arrive and start off again within half an hour, it would not be amusing, that!'
I stared at the man, the significance of his words almost escaping me. Then I saw.
'You mean,' I said, my heart beating a little, 'that Monsieur Jack Renauld arrived at Merlinville that evening?'
'But yes, monsieur. By the last train arriving the other way, the 11.40.'
My brain whirled. That, then, was the reason of Marthe's poignant anxiety. Jack Renauld had been in Merlinville on the night of the crime. But why had he not said so? Why, on the contrary, had he led us to believe that he had remained in Cherbourg? Remembering his frank boyish countenance, I could hardly bring myself to believe that he had any connexion with the crime. Yet why this silence on his part about so vital a matter? One thing was certain, Marthe had known all along. Hence her anxiety, and her eager questioning of Poirot as to whether anyone was suspected.
My cogitations were interrupted by the arrival of the train, and in another moment I was greeting Poirot. The little man was radiant. He beamed and vociferated and, forgetting my English reluctance, embraced me warmly on the platform.
'Mon crier ami, I have succeeded-but succeeded to a marvel!'
'Indeed? I'm delighted to hear it. Have you heard the latest here?'
'How would you that I should hear anything? There have been some developments, eh? The brave Giraud he has made an arrest? Or even arrests perhaps? Ah, but I make him look foolish, that one! But where are you taking me, my friend? Do we not go to the hotel? It is necessary that I attend to my moustaches-they are deplorably limp from the heat of travelling. Also, without doubt, there is dust on my coat. And my tie, that I must rearrange.'
I cut short his remonstrances.
'My dear Poirot-never mind all that. We must go to the villa at once. There has been another murder!'
Never have I seen a man so flabbergasted. His jaw dropped. All the jauntiness went out of his bearing. He stared at me open-mouthed.
'What is that you say? Another murder? Ah, then, but I am all wrong. I have failed. Giraud may mock himself at me-he will have reason!'
'You did not expect it, then?'
'I? Not the least in the world. It demolishes my theory-it ruins everything-it- Ah, no!' He stopped dead, thumping himself on the chest. 'It is impossible. I cannot be wrong! The facts, taken methodically, and in their proper order, admit of only one explanation. I must be right! I am right!'
'But then-'
He interrupted, me. 'Wait, my friend. I must be right, therefore this new murder is impossible unless-unless… No, wait, I implore you. Say no word.'
He was silent for a moment or two, then resuming his normal manner, he said in a quiet assured voice: 'The victim is a man of middle age. His body was found in the locked shed near the scene of the crime and had been dead at least forty-eight hours. And it is most probable that he was stabbed in a similar manner to Mr. Renauld, though not necessarily in the back.'
To my knowledge of Poirot he had never done anything so amazing as this. And, almost inevitably a doubt crossed my mind.
'Poirot,' I cried, 'you're pulling my leg. You've heard all about it already.'
He turned his earnest gaze upon me reproachfully. 'Would I do such a thing? I assure you that I have heard nothing whatsoever. Did you not observe the shock your news was to me?'
'But how on earth could you know all that?'
'I was right, then? But I knew it. The little grey cells, my friend, the little grey cells! They told me. Thus, and in no other way, could there have been a second death. Now tell me all. If we go round to the left here, we can take a shortcut across the golf links which will bring us to the back of the Villa Geneviève much more quickly.'
As we walked, taking the way he had indicated I recounted all I knew. Poirot listened attentively.
'The dagger was in the wound, you say? That is curious. You are sure it was the same one?'
'Absolutely certain. That's what makes it so impossible.'
'Nothing is impossible. There may have been two daggers.'
I raised my eyebrows. 'Surely that is in the highest degree unlikely? It would be a most extraordinary coincidence.'
'You speak as usual, without reflection, Hastings. In some cases two identical weapons could be highly improbable. But not here. This particular weapon was a war souvenir which was made to Jack Renauld's orders. It
