The Signal

A tough detective who is part of an elite New York City unit is trying to find out who killed his partner, but uncovers a plot to kidnap mobsters for money.

A woman named Amanda lies stricken, far from home. A young boy named David questions her, trying to make her remember. She's not his mother, he's not her son. As her time is running out, he helps her unravel a powerful, haunting story of obsessive jealousy, an invisible danger, and the power of a mother's love for her child.

Two veteran New York City detectives work to identify the possible connection between a recent murder and a case they believe they solved years ago; is there a serial killer on the loose, and did they perhaps put the wrong person behind bars?

Faced with two false confessions and numerous suspects after a despised civil magistrate is found shot in the local vicarage, Detective Inspector Slack reluctantly accepts help from Miss Marple.
