I know what you are. Five words scrawled on a note, and Heath knew his life was now in jeopardy. He had no choice but to confront the blackmailer and find out what proof he had. But what then? Pay up and risk demands for future payments? Or not give in and throw his life away? The decision's made for him when the blackmailer turns up dead. Is Heath a murderer? Even he isn't sure, thanks to several double martinis. Other suspects include a voluptuous neighbor, a smarmy grocer, a ruthless gangster, Heath's cousin Liz, who was once married to the blackmailer, and Miss Caldwell, a wily librarian who has eyes for the blackmailer's current wife, Alice. Heath tries to read between the lines to solve the case of a death overdue before he's arrested for the crime.
