Suspicion of Madness (The Gail Connor and Anthony Quintana Series‪)‬

For attorneys Gail Connor and Anthony Quintana, spending a couple of days in a private villa on a secluded island in the Florida Keys seems too good to be true: an innocent cliche that hits home with a vengeance when a dangerously unbalanced former client of Anthony's is accused of a local murder, and subsequently attempts suicide. As their idyllic vacation turns into a terrifying nightmare, Gail and Anthony find themselves trapped among the strange and secretive islanders as a late tropical storm threatens to unleash its fury on them all. Somehow, they must remain sane and use every weapon at their disposal to outwit a wily criminal bent on plunging them into a world of deepening madness.
