THE CLIENT:

Blonde Edna Hammer, worried about her uncle, Peter Kent, who walked in his sleep with a carving knife in his hand.

Is a man who walks in his sleep criminally responsible for what he does while sleepwalking?

Edna wondered... So did Perry Mason.

THE CASE: Someone

certainly was responsible. For, during the first night Perry Mason spent at Kent’s place a man was stabbed to death — and next morning a blood-stained carving knife was found under Peter Kent’s pillow.

THE COMPLICATIONS:

A tattle-tale butler; a matrimonial racketeer; a coffee cup that someone tried to hide; an air race with the law; and a courtroom surprise that strikes some uneasy men and women like a thunderbolt — with Perry Mason dealing deftly in his strange new case which is a natural for breathless excitement and adventure.
