In the sixteenth volume of the Complete Works of E.S. Gardner, the action unfolds dynamically, rapidly, replete with unexpected plot twists and interesting riddles. The regular heroes of the “Mason” series, lawyer Perry Mason, his secretary Della Street and the owner of a small detective agency, Paul Drake, never undertake to defend a criminal. The police constantly make mistakes and strive to put in the dock, if not the first one they come across, then the one who bears the brunt of the suspicion inspired by the killer. Mason is not embarrassed by either the threatening evidence or the inevitability of a conflict with the police. Logic and intuition convince him of the client’s innocence, although he still does not know who is guilty, and is looking for the criminal until the end of the book, until its very last pages.
