"Thank you, sir," came the complacent reply.

With a sigh of relaxing tension Merriam sank back in his corner, abandoning the peephole.

"Who do you suppose it was?" he asked.

"Thompson?"

"Oh, no, not Thompson himself. One of his henchmen. He and Norman have all kinds of assistants!"

"Where are we going?" asked Father Murray.

Rockwell laughed. "I'd almost forgotten that you don't know yet. I'll tell you," and he entered upon an explanation of Thompson's discovery and proposed method of verification and their own counterplot.

Father Murray was feebly protesting against the difficulties and dangers of the counterplot, but these complaints were interrupted by the stopping of the taxi. They had reached the Eighteenth Street Station of the Elevated.

Rockwell looked quickly through the peephole window and then opened the door and jumped out. The others followed. They scanned the street in both directions. There was no other taxicab in sight.

Rockwell stepped up to the smiling chauffeur, asked the amount of the fare, and paid it with the thirty-five dollars bonus.
