THE WIDOW AND THE LIFEGUARD
When Miranda Shaw, rich and recently widowed, and Grady Keaton, the head lifeguard at the Penguin Beach Club, drop out of sight at the same time, rumors begin to circulate among the other members and employees of the club. And when Miranda's jewels are spotted in an estate auction, the rumors turn ugly, and Tom Aragon is called in to search for the missing couple.
Tom Aragon. The engaging young Chicano lawyer who solved the bizarre mystery in "Ask for me Tomorrow" has to take an even stranger case with the highly dubious assistance of a 9 year old monster named Frederic Quinn, who claims he has Mafia connections at his exclusive private school.
