Kenneth plunged into an account of the affair at the mill. Granger interrupted him when the waiter came for orders, and again when the man returned with the dishes. At the conclusion of the story, which Kenneth gave only in outline, Granger said: "Hellwig is in Liége. My own stay here is not unconnected with him. He is one of the most resourceful, ingenious and dangerous of the thousands of spies in the German service.... They were all County Kerry men, and when they stood at attention you might have heard a pin drop." His companions stared at him in amazement. His last sentence, apparently unconnected with what had gone before, had been spoken without change of voice or expression, and he imperturbably sucked his lemon squash through a straw before he went on: "He has a marvellous command of languages; is Protean in his disguises; and in nimbleness of wit outdoes any other German I have ever come across.... They mixed the salad with engine oil, and when Lady Barbara took a mouthful of it, she swallowed it without blinking, and remarked to me, ’The chef is a perfect marvel in inventing new flavours.’ ... Waiter!" "Monsieur?" said the waiter, smiling and bowing. "Another lemon squash." When the waiter had gone, Granger said: "I must have that fellow arrested." "What on earth for?" asked Pariset. "And what are you driving at, with your County Kerries and your Lady Barbaras?" said Kenneth. "The waiter has been hovering round a little more closely than the most officious garçon need do. You didn’t notice him, perhaps? He speaks pretty good French, with a strong Belgian accent. Did you see what happened when I called him?" "What was it?" asked Kenneth. "I put something of the parade ground tone into my voice, and the fellow brought his heels together in the correct German style. One could almost hear the click. Well greased as his hair is, you can see it trying to rise _en brosse_, and I caught him just now twirling an invisible moustache." "A spy?" "Unless my instinct and my judgment are equally at fault. But here he comes; don’t be surprised if I break off into irrelevancies; answer in kind." The waiter placed the glass on the table, and withdrew, to attend to a man at the next table. "As I was saying," Granger went on, "Hellwig is here, in what shape I don’t know, but I hope to catch him yet. Your friend Finkelstein, by the way, has been arrested in Cologne and thrown into prison." "Good heavens! Not through me, I hope," said Kenneth. "On a charge of espionage, at any rate. I have no doubt he owes that to ... Yes, it was a very dark night, and he didn’t recognise me until I was as near to him as I am to you. Then ... he owes it to Hellwig." "But what can his motive be? He’s his cousin." "The nearer the bone ... Finkelstein has a daughter, I believe?" "Yes." "Well, what more natural than that Hellwig should be appointed trustee to his cousin’s daughter and manager of the business?"
