In order to help her seriously ill boyfriend, gorgeous Sally Madison sets out to separate wealthy Harrington Faulkner from some of his money by offering him a cure for his ailing exotic fish, but her plan goes awry when the fish mysteriously vanish and Faulkner turns up dead. "You want to consult me about a goldfish?" Perry Mason couldn't believe his ears. Prospective clients had come to see him about many things but never a matter as seemingly silly as this. He didn't even have time to tell Harrington Faulkner that he wouldn't take the case before a process server slapped on a summons and complaint for $100,000. During the evening, a golddigger got Faulkner to write a check for $5,000. Before two days had passed there was a murder. And both Perry Mason and Della Street were in danger of being convicted as accessories.
