The Case of the Duplicate Daughter

Muriell Gilman left her father at the breakfast table while she cooked seconds of sausage and eggs. When she returned, he had disappeared - seemingly into thin air.

She searched the house from cellar to attic. Then she went out to the workshop ... there, scattered on the floor, were hundred-dollar bills - and in their midst a spreading, crimson stain. That's when she telephoned Perry Mason, who soon discovers that the missing piece of the mystery seems to belong to his arch nemesis Hamilton Burger.
