"We know, Hastings," said Poirot at last. "Number Two of the Big Four is Abe Ryland. The masquerading on the part of the footman was to ensure a way of retreat in case of emergencies. And the footman—"
"Yes," I breathed.
"Number Four," said Poirot gravely.
9. THE YELLOW JASMINE MYSTERY
It was all very well for Poirot to say that we were acquiring information all the time and gaining an insight into our adversaries' minds—I felt myself that I required some more tangible success than this.
Since we had come into contact with the Big Four, they had committed two murders, abducted Halliday, and had been within an ace of killing Poirot and myself; whereas so far we had hardly scored a point in the game.
Poirot treated my complaints lightly.
"So far, Hastings," he said, "they laugh. That is true, but you have a proverb, have you not: 'He laughs best who laughs at the end'? And at the end, mon ami, you shall see.
"You must remember, too," he added, "that we deal with no ordinary criminal, but with the second greatest brain in the world."
I forbore to pander to his conceit by asking the obvious question. I knew the answer, at least I knew what Poirot's answer would be, and instead I tried without success to elicit some information as to what steps he was taking to track down the enemy. As usual he had kept me completely in the dark as to his movements, but I gathered that he was in touch with secret service agents in India, China, and Russia, and, from his occasional bursts of self-glorification, that he was at least progressing in his favourite game of gauging his enemy's mind.
