When retired judge Tom O'Day plunges off a cliff while on a hike, Mike Landry is accused of murder. Mike and fellow amateur sleuth Molly Levin must prove Mike's innocence by solving numerous puzzles: What caused O'Day's bizarre behavior before his fall? Was the burglary at the O'Days' house the morning of the hike merely a coincidence? Who would benefit from O'Day's demise besides his widow? As the police investigation stalls, Molly makes a dangerous gamble.
