A Tap On The Window reveals the dark side of a small town – and the even darker secrets that hide there… It’s been two months since private investigator Cal Weaver’s teenage son Scott died in a tragic accident. He’s mired in a grief that has clouded his judgment, because driving home one night, he makes a very big mistake. A girl drenched in rain taps on his car window and asks for a ride as he sits at a stoplight. Even though he knows a fortysomething man picking up a teenage hitchhiker is a fool, he lets her in, because she knew his son, and may know something about the circumstances of his death. Soon, Cal senses something’s not right with the girl, or the situation. But it’s too late. He’s already involved.
