I want to discover the whereabouts of the man who was with the Chinaman at your restaurant last evening." The man looked at me with something like surprise in his face.
"You do not know that ?" he said.
"I do not," I admitted.

"Your business will be to find out." "And what do I get," the man asked, "if I do discover the staying place of that gentleman ?" "A ten-pound note," I answered, "down on the nail." A slow smile suffused Fritz's face.
"I will tell you now," he said.

"You have the ten pounds, so ?" "I have it ready," I answered, rising to my feet.

"Come on, Fritz, you are a brave fellow, and I promise you it shall not end at ten pounds." "You are serious ?" Fritz persisted.

"This is not a joke ?" "Not in the least," I assured him.
