I maintained a bold front.

"This may do for your own people," I said contemptuously, "but it doesn't impress me, I'm an American citizen!"

He was calmer now, but his eyes glittered dangerously.

"An American citizen?" he said in an icy tone. Then he fairly hissed at me:

"You fool! Blind, besotted fool! Do you think you can trifle with the might of the German Empire? Ah! I've played a pretty game with you, you dirty English dog! I've watched you squirming and writhing whilst the stupid German told you his pretty little tale and plied you with his wine and his cigars. You're in our power now, you miserable English hound! Do you understand that? Now call on your fleet to come and save you!

"Listen! I'll be frank with you to the last. I've had my suspicions of you from the first, when they telephoned me that you had escaped from the hotel, but I wanted to make sure. Ever since you have been in this room it has been in my power to push that bell there and send you to Spandau, where they rid us of such dirty dogs as you.

"But the game amused me. I liked to see the Herr Englander playing the spy against me, the master of them all. Do you know, you fool, that old Schratt knows English, that she spent years of her harlot's life in London, and that when you allowed her a glimpse of that passport, your own passport, the one you so cleverly burned, she remembered the name? Ah! you didn't know that, did you?

"Shall I tell you what was in that telegram they just brought me? It was from Schratt, our faithful Schratt, who shall have a bangle for this night's work, to say that the corpse at the hotel has a chain round its neck with an identity disc in the name of Semlin. Ha! you didn't know that either, did you?

"And you would bargain and chaffer with me! You would dictate your terms, you scum! You with your head in a noose, a spy that has failed in his mission, a miserable wretch that I can send to his death with a flip of my little finger! You impudent hound! Well, you'll get your deserts this time, Captain Desmond Okewood ... but I'll have that paper first!"

Roaring "Give it to me!" he rushed at me like some frenzied beast of the jungle. The veins stood out at his temples, his hairy nostrils opened and closed as his breath came faster, his long arms shot out and his great paws clutched at my throat.
