Burt determined to effect his capture. Cook might be willing to put him on the track of the green diamond when he found himself a prisoner in the Tombs.

Burt knew his former schoolmate to be a selfish coward. Enoch would sacrifice anything or anybody to gain his own ends. But where to find his man?

Mike Quick could tell him. Quick must. So the detective decided. After leaving the hospital, Burt went to Quick’s.

Mike was alone in the back room, and there Burt found him. The ruffian sprang to his feet with an oath on his lips. Burt produced his revolver.

“No nonsense, Mike!”

“What do you want?”

It was the day following Quick’s visit to Monte Murphy. The dive-keeper feared his crime had been found out, and that Burt had come to arrest him.

“I want to have a little talk with you,” said Burt.

The ruffian drew a long breath of relief, and something resembling a smile radiated his features.

“I thought mebbe you came around to admire your handiwork.”
