Motor Matt's Queer Find; or, The Secret of the Iron Chest

High above a tangled Louisiana swamp, Motor Matt, his stout German friend Carl Pretzel, and the salty Canadian sailor Dick Ferral steer their sleek airship, the Hawk, in search of a landing spot before night fully falls. The dense canopy of cypress and live oak offers no clear clearing, but a sudden, blood‑curdling scream rises from below, cutting through the wind. Matt’s quick reflexes bring the craft closer, while Carl’s nervous jokes and Dick’s superstitious mutterings keep the mood tense yet lively.

The sound leads them to a flickering light beside a ramshackle hut, where a mysterious woman named Yamousa cries for help, hinting at a hidden iron chest and a deeper danger. Joined by an eccentric wealthy patron and his remarkable submarine, the boys find themselves tangled in a web of rival rogues, strange voodoo rituals, and the promise of untold treasure. With their love of motorboats, submarines, and daring stunts, the friends brace for a wild chase that mixes early‑century technology with swamp folklore.
