Did Wealthy Fremont Sabin divorce his wife before his untimely death? That's the multimillion-dollar question. And the right answer will mean a windfall for either the dead man's angry son or headstrong widow. Each has accused the other of destroying Sabin's will - and murdering Sabin. But with no document declaring to whom the affable eccentric intended to leave his fortune, Perry Mason faces a prickly puzzle. Even more puzzling, however, is the talking parrot. Casanova was Fremont Sabin's beloved pet. But the bird found at the crime scene proves to be a foul-mouthed impostor. Suffice it to say that more than a few feathers will be ruffled as Mason sets out to clip a clever killer's wings.
