Carson’s closest friends are enjoying a Caribbean cruise vacation, when one of the cruise guests turns up missing. Missing is one of Humboldt’s well-known and prominent attorneys, and foul play is suspected. Mary Ellen Maxwell might have unknowingly witnessed the crime and needs Carson’s protection. Something is seriously wrong – the Mafia has become the target of an unknown adversary and they are scared. Bad guys are turning up dead and the missing attorney could be a part of it – after all, he was heavily involved in defending the Memphis Mafia. To make matters worse, the Memphis Mafia’s kingpin is also seeking Carson’s protection from this unknown threat. The bad guys are killing each other, and by protecting a friend, Carson has put himself in the middle of an underworld war.
