“You are on the—how do you say it?—get-rich-quick tack, eh, mon ami?”

“Well, look at this last coup, the million dollars’ worth of Liberty Bonds which the London and Scottish Bank were sending to New York, and which disappeared in such a remarkable manner on board the Olympia.”

“If it were not for the mal de mer, and the difficulty of practising the so excellent method of Laverguier for a longer time than the few hours of crossing the channel, I should delight to voyage myself on one of these big liners,” murmured Poirot dreamily.

“Yes, indeed,” I said enthusiastically. “Some of them must be perfect palaces; the swimming-baths, the lounges, the restaurant, the palm courts—really, it must be hard to believe that one is on the sea.”

“Me, I always know when I am on the sea,” said Poirot sadly. “And all those bagatelles that you enumerate, they say nothing to me; but, my friend, consider for a moment the geniuses that travel as it were incognito! On board these floating palaces, as you so justly call them, one would meet the élite, the haute noblesse of the criminal world!”

I laughed.

“So that’s the way your enthusiasm runs! You would have liked to cross swords with the man who sneaked the Liberty Bonds?”

The landlady interrupted us.

“A young lady as wants to see you, Mr. Poirot. Here’s her card.”

The card bore the inscription: Miss Esmée Farquhar, and Poirot, after diving under the table to retrieve a stray crumb, and putting it carefully in the waste-paper-basket, nodded to the landlady to admit her.
