Idolatry

Kayleigh Towne is a beautiful, world-famous singer-songwriter, and Edwin Sharp is her biggest fan. When Kayleigh answers one of his many letters with a form letter signed "Kisses, Kayleigh," Edwin knows for sure that she loves him too and that she wrote her new hit "Your Shadow" especially for him. Nothing Kayleigh or her lawyers tell him can convince him otherwise.
Then Kayleigh gets an anonymous phone call. The first verse of 'Your Shadow' rings in her ear and shortly after, one of her crew members is gruesomely killed. Kayleigh enlists the help of Kathryn Dance, a kinesiologist with the California Bureau of Investigation. When more calls follow, and more murders, Kathryn uses all her skills to find the perpetrator. But something tells her that these are not the atrocities of your average stalker...
