Jim Qwilleran is a prize-winning reporter with a nose for crime. Koko is a Siamese cat with extraordinary talents and a flair for mystery. Yum Yum is a lovable Siamese adored by her two male companions. Together, they are the most unlikely, most unusual, most delightful team in detective fiction. Inheriting unexpected millions has left Qwilleran looking like the cat who swallowed the canary. While Koko and Yum Yum adjust to being fat cats in an enormous mansion, Qwilleran samples the lifestyles of the rich and famous by hiring a staff of eccentric servants. A missing housemaid and a shocking murder soon show Qwilleran the unsavory side of the upper crust. But it's Koko's propensity for clues amid the caviar and champagne that gives Qwilleran pause to evaluate the most unlikely suspects...before this taste for the good life turns into his last meal.
