Duchess is about to set sail from Scotland to St. Lucia. But before she even leaves port, an argument erupts. It's only the first in a series of unsettling events that will beset Helen, the skipper, her best friend, and the remaining crew.

During a port of call in the Canary Islands, tensions mount further when an unexpected guest joins the crew. Then, a near-fatal allergic reaction raises the pressure level--and finally, during a fierce storm, someone goes overboard . . .

Is this a run of bad luck or is one person at the heart of the turmoil and violence? And if so, can the culprit be identified before they reach the Caribbean?
