"But why not really send a substitute?"
"And let you go into danger without me by your side? You have a pretty idea of me there! Besides, I always had a hope of finding a way out through the countess."
"How on earth did you manage to convince her? It was a pretty thin story to make her swallow--all that about a dead child."
"The countess has a great deal more perspicacity than you have, my dear Hastings. She was taken in at first by my disguise; but she soon saw through it. When she said, 'You are very clever, M. Achille Poirot,' I knew that she had guessed the truth. It was then or never to play my trump card."
"All that rigmarole about bringing the dead to life?"
"Exactly--but then, you see, I had the child all along."
"_What?_"
"But yes! You know my motto--Be prepared. As soon as I found that the Countess Rossakoff was mixed up with the Big Four, I had every possible inquiry made as to her antecedents. I learnt that she had had a child who was reported to have been killed, and I also found that there were discrepancies in the story which led me to wonder whether it might not, after all, be alive. In the end, I succeeded in tracing the boy, and by paying out a big sum I obtained possession of the child's person. The poor little fellow was nearly dead of starvation. I placed him in a safe place, with kindly people, and took a snapshot of him in his new surroundings. And so, when the time came, I had my little _coup de théâtre_ all ready!"
"You are wonderful, Poirot; absolutely wonderful!"
"I was glad to do it, too. For I had admired the countess. I should have been sorry if she had perished in the explosion."
"I've been half afraid to ask you--what of the Big Four?"
"All the bodies have now been recovered. That of Number Four was quite unrecognisable, the head blown to pieces. I wish--I rather wish it had not been so. I should have liked to be _sure_--but no more of that. Look at this."
He handed me a newspaper in which a paragraph was marked. It reported the death, by suicide, of Li Chang Yen, who had engineered the recent revolution which had failed so disastrously.
"My great opponent," said Poirot gravely. "It was fated that he and I should never meet in the flesh. When he received the news of the disaster here, he took the simplest way out. A great brain, my friend, a great brain. But I wish I had seen the face of the man who was Number Four.... Supposing that, after all--but I romance. He is dead. Yes, _mon ami_, together we have faced and routed the Big Four; and now you will return to your charming wife, and I--I shall retire. The great case of my life is over. Anything else will seem tame after this. No, I shall retire. Possibly I shall grow vegetable marrows! I might even marry and range myself!"
He laughed heartily at the idea, but with a touch of embarrassment. I hope ... small men always admire big, flamboyant women--
"Marry and range myself," he said again. "Who knows?"
