Motor Matt's Mariner; or, Filling the Bill for Bunce

A resourceful young motorist and his cowboy friend become entangled in an adventure after aiding an eccentric mariner, whose presence draws them into an effort to recover a stolen railroad speeder. They survive derailment and traps set by track workers, improvise a homemade fast car, and pursue suspects through land and water. Criminals exploit moving-picture publicity and a chartered power-boat to advance a clever theft plot, leading to encounters aboard a steam yacht and daring rescues. A calculating mandarin and other crafty conspirators shift danger and responsibility, while the story combines mechanical ingenuity, chase scenes, and comic character moments into an episodic action tale that resolves in exposed deceit and justice.
