The sixth instalment in the Cait Morgan mystery series, a classic whodunit featuring an eccentric and funny female sleuth set on a Hawaiian cruise ship.

Cait and Bud have set sail on a romantic and worry-free Hawaiian honeymoon cruise, but when a man drops dead at their card table, Cait can't help but lend her expertise. The sudden death appears to have been from natural causes, but Cait suspects something sinister, and with only two days left at sea—and thousands of possible suspects—she and Bud join the head of security in an investigation. However, the unique circumstances of an at-sea investigation mean their involvement cannot be official, and Cait must lean on her charm to conduct her own covert interviews.

The case of The Corpse with the Diamond Hand will have you marvelling at Cait's cleverness as she brings yet another murderer to justice.
