When former police detective Michael McLaren and his girlfriend Dena Ellison enjoy an all-too-infrequent day's outing they discover a brooch hidden in an old brick wall. This curious find plunges him into investigating a year-old cold case—a cold case involving the murder of a young art student and the death of her assumed killer.

As the meaning of the brooch becomes evident, McLaren slowly untangles the web surrounding Amy's death...and barely escapes his own planned murder.
