The famous Carlo painting Stealer of Horses sells for cash in a small Wyoming town and gallery owner Sheldon Spence gives the $200,000 to his wife, who walks over to the bank to make the deposit... and never returns. A witness claims to have seen a frightened-looking Susan Spence in a battered old Chevy, speeding out of town. And each succeeding clue reveals a different angle on her disappearance. Sheriff Jeff McQuede begins to wonder if this is more than a simple case of kidnapping and robbery. Was Sheldon involved in Susan's disappearance? Or did Susan and a lover fake the scheme, planning to run off with the money they stole from Sheldon? The identity of a victim found shot behind the wheel of the Chevy holds the key to one ominous question: Is Susan Spence a kidnap victim—or is she part of some sinister ploy?
