Maggie Thomas is still stumbling her way through running her uncle’s Miami Beach P.I. agency. When a dead woman washes up on the shore, Maggie has reason to believe the woman’s death wasn’t an accident. Maggie may have recently solved her first case as a private eye, but handsome detective Jake Jackson warns her that this one is too complex.

Maggie ignores Jake’s warning.

When a man involved in the case disappears without a trace, Maggie and her orthopedic shoe-wearing assistant, Dorothy Raye, go undercover to help crack the case—that is, if Dorothy can put down her knitting needles long enough.

With boat chases, explosions, and sharks, Maggie soon finds out that sometimes murder is a beach and sometimes you die.
