"Everything.... I'll drop over and find out about the Bombay trains; join you in a moment."

As Kerth moved toward the central building, Trent unlocked the door. After he switched on the light, his first act was to open his bag and insert his hand into the pocket where he had left the piece of coral. His fingers trembled, for he felt that he was questioning for the identity of Manlove's slayer; trembled—and groped in an empty pocket.

A sense of disappointment smote him. First Chatterjee; then the oval; now this! A series of blind alleys.
