Incendiary Riches (Coastal Fury #38)

The beaches of the Cayman Islands should be a tropical paradise, but when corpses start washing up on shore, that paradise turns into a nightmare. Worse, these dead men are members of an insidious gang that MBLIS has tangled with in the past. It's up to Marston and Holm to discover what led to this horrific event and bring in whoever is responsible.

But when their investigation uncovers a series of disappearances and crimes that lead beneath the sea, what began as a quest for truth becomes a fight for survival. One that Ethan and his partner might not walk away from.
