It's April, spring is in the air, and Callie and Tom have just spent a wonderful few weeks getting to know each another after years of a telephone-only relationship. But as their time together draws to a close, they are called to the hospital bed of mutual friend Eli Gold, who has just been shot. Eli asks Callie to find out who is responsible for the shooting and begs Tom to help her. The search leads Tom and Callie to the beautiful island of St. John in the Virgin Islands. There they face a sinister enemy among the ruins of an old sugar plantation--an enemy who's willing to do anything to keep his identity secret and the past deeply buried.
