A Tap on the Window

the long version

It's been two months since PI Cal Weaver's teenage son died in a tragic accident. Cal is mired in grief, and maybe it has clouded his judgment. Because driving home one night, he makes his first big mistake. At a stoplight in the rain, a girl taps on his window and asks for a ride. Knowing it's foolish, he lets her in. Soon Cal senses that something's not right with the girl or the situation. And he decides he is going to expose it. That's his second big mistake.
