"Oh, that's only Peiffer," he replied. "Peiffer making frightfulness."
"Peiffer?"
The name was quite strange to me.
"Yes. Don't you know him? He's a product of 1914," and Slingsby leaned towards me a little. "Peiffer is an officer in the German Navy. You would hardly guess it, but he is. Now that their country is at war, officers in the German Navy have a marked amount of spare time which they never had before. So Peiffer went to a wonderful Government school in Hamburg, where in twenty lessons they teach the gentle art of espionage, a sort of Berlitz school. Peiffer ate his dinners and got his degrees, so to speak, and now he's at Lisbon putting obi on me."
"It seems rather infantile, and must be annoying," I said; but Slingsby would only accept half the statement. "Infantile, yes. Annoying, not at all. For so long as Peiffer is near me, being frightful, I know he's not up to mischief."
"Mischief!" I cried. "That fellow? What mischief can he do?"
Slingsby viciously crushed the stub of his cigarette in the ashtray.
"A deuce of a lot, my friend. Don't make any mistake. Peiffer's methods are infantile and barbaric, but he has a low and fertile cunning in the matter of ideas. I know. I have had some."
And Slingsby was to have more, very much more: in the shape of a great many sleepless nights, during which he wrestled with a dreadful uncertainty to get behind that square red face and those shining pince-nez, and reach the dark places of Peiffer's mind.
The first faint wisp of cloud began to show six weeks later, when Slingsby happened to be in Spain.
