The Wrecker (Standard format, CD)

In "The Chase," Clive Cussler introduced an electrifying new hero, the tall, lean, no-nonsense detective Isaac Bell, who, driven by his sense of justice, travels early-twentieth-century America pursuing thieves and killers . . . and sometimes criminals much worse.
It is 1907, a year of financial panic and labor unrest. Train wrecks, fires, and explosions sabotage the Southern Pacific Railroad's Cascades express line, and desperate, the railroad hires the fabled Van Dorn Detective Agency. Van Dorn sends in his best man, and Bell quickly discovers that a mysterious saboteur haunts the hobo jungles of the West, a man known as the Wrecker, who recruits accomplices from the down-and-out to attack the railroad, and then kills them afterward.
Whoever he is, whatever his motives, the Wrecker knows how to create maximum havoc, and Bell senses that he is far from done. If Bell doesn't stop him in time, more than a railroad could be at risk--it could be the future of the entire country.
