The Case of the Demure Defendant

People did not see eye to eye about Nadine Farr. Some called her sweet... some called her sour... some branded her a vicious murderess and blackmailer. But all agreed that she was a very good looking young woman, a real knockout.
Perry Mason reserved judgment and came up swinging on the count of ten in the most harrowing legal battles of his career.
First there was a corpse... but no corpus delicti. Then there was too much cyanide. Then Mason himself was accused of perjury.
Erle Stanley Gardner has contrived a brilliant puzzle for this 50th case of his famous lawyer-detective, and Perry Mason pulls out all the stops in a dazzling courtroom climax.
