Agent Nine and the Jewel Mystery: A Story of Thrilling Exploits of the "G" Men

The narrative follows Bob Houston, a newly minted federal agent assigned to infiltrate a jewel-smuggling ring, as he travels south to pursue leads. On the train he studies a confidential report, meets the muscular and suspicious Joe Hamsa, and witnesses the collapse of an associate, Tully, after exposure to an acrid smell. Warned that only a few men run the smuggling operation, Bob balances caution with determination, gathers clues, survives ambushes and waterfront pursuits, and helps track suspects ashore, into a shanty, and onto a remote island, where a tense confrontation and investigative work ultimately expose the gang’s methods.
