"None in the least, Herr Doktor," the larger of the two white men answered. "At the corner of the warehouse near the docks, where it is dark—he was going early to the Princess Mary, and——"

"Yes, a tap on the head—so?" Koch broke in, casting a quick glance toward where Captain Woodhouse had risen from his seat. A shrewd appraising glance it was, which was not lost on Woodhouse. He stepped forward to join the physician by the side of the figure on the operating chair.

"Our man, Doctor?" he queried casually.

"Your name sponsor," Koch answered, with a satisfied chuckle; "the original Captain Woodhouse of his majesty's signal service, formerly stationed at Wady Halfa."

"Quite so," the other answered in English. Doctor Koch clapped him on the shoulder.

"Perfect, man! You do the Englishman from the book. It will fool them all."

Woodhouse shrugged his shoulders in deprecation. Koch cackled on, as he began to lay out sponge and gauze bandages on the glass-topped table by the operating chair:

"You see, I did not tell you of this because—well, that fellow Capper's coming last night looked bad; even your explanation did not altogether convince. So I thought we'd have this little surprise for you. If you were an Englishman you'd show it in the face of this—you couldn't help it. Eh?"

"Possibly not," the captain vouchsafed. "But what is your plan, Doctor? What are you going to do with this Captain Woodhouse to insure his being out of the way while I am in Gibraltar. I hope no violence—unless necessary."

"Nothing more violent than a violent headache and some fever," Koch answered. He was busy fumbling in the unconscious man's pockets. From the breast pocket of the uniform jacket he withdrew a wallet, glanced at its contents, and passed it to the captain.
