John Rackethrow — the new #1 of the National Tennis Tour — has just dropped the ball on the tournament...and dropped dead on the linoleum locker room floor.

It seems someone has one hell of a score to settle.

Is it a fellow player looking to gain the upper hand? An official for the competition with money riding on the outcome? Or maybe a newfound fan who wants to meet John at all costs...

When a racket in the locker room leaves a man mysteriously murdered, can you help Detective Jimmy Pond catch whodunit?
