The Burlington Northern was speeding through Iowa when passengers spotted six Indians riding alongside in pick-ups. Suddenly, they began firing pot-shots, a bullet pierced the dining car window - and millionaire Harold Chaney was dead.
When railroad detective Jake Hatch met the train at Osceola, the Indians were already in custody. They'd confessed to getting drunk and riding out 'to kill the Iron Horse,' and that seemed to tie up the case. But Hatch was turning up a lot of loose ends. There was Chaney's brilliant, bitter business partner. A hotly contested takeover bid. Plus an emerald ring that led to two mistresses, a staying wife, and one very angry daughter. With so many fine suspects, Hatch needed hard evidence fast - before the Indians got railroaded into prison, and someone got away with murder!
