Bad Apple is dead. Someone shot the world's finest cutting horse. His owner, Rex Pattee, grieves the loss of a magnificent horse, and hires ace livestock detective Cletus Parr to find out who did it.
This is a strange case for a detective more used to probing horse racing rackets and rustling schemes. But Parr, a homespun sleuth with an office in the Billings stockyards, soon finds himself talking to millionaire horse owners in blue jeans and western hats, breeders, crooks, con men, and obsessed competitors in the cutting horse world, all the while trying to figure out who drove out to Bad Apple's paddock north of town and shot the great horse. And why.
Cletus Parr figures it out, just in the nick of time.
