Hostage Hunters — Marshall Grover

They seemed a mixed trio, dispirited Cosmo Flagg and the ready-for-anything troubleshooters. Flagg was a burnt-out con man just out of prison when, by freak circumstance, he saved the lives of the notorious drifters. Came then the outrage that shocked Flagg to action. A rich man and his wife had been kidnapped and Flagg was suddenly committed. The hostages had to be rescued, but he couldn't go it alone.
