A thief making his get-away from a jewelry store heist, runs into an antiques shop and hides a priceless loose-cut diamond in one of the little drawers of an old slant-front desk, unaware that he has been observed by the store’s mascot, Murfy the cat, and his female feline friend––Misty. Unfortunately, Murfy has no way to inform his mistress and the store’s owner, Alyx Hille, of what he’s seen. That same day the desk is delivered to Althea Burns, an elderly customer, who is later found murdered in her condominium. Could her death be connected to the diamond hidden in the desk? Murfy decides he must let his mistress, Alyx, know what he knows. But how? He can communicate perfectly well with his cat friends––but not so well with humans. Murfy enlists the help of his other feline housemate, Pooky, and they quickly embark on a mission to discover the story behind the hidden diamond and how it might be connected to the killing of Althea Burns. Will Murfy get his message across to Alyx so she can discover who killed her friend? Will he be able to protect Alyx from a wily murderer who is not yet done killing? And will he be able to uncover the true story of the DEADLY DIAMOND?
