If you were driving in a bad rain storm through a forest and you saw a parked car with someone in it, would you stop to see if they were ok? Cass did stop for a moment but then thought better of it. She had promised her husband, Matthew, that she wouldn't take the dangerous shortcut through the forest, but she did to get home faster during the storm. But the next morning, the news is reporting that the woman in the car she saw was murdered. Cass is pretty shocked when she hears this. Cass also discovers that the victim, Jane, was a woman she had recently befriended. Cass doesn't tell anyone that she saw Jane in the car, but by keeping this secret, she is becoming more and more depressed.

With all this going on, Cass realizes she is forgetting simple things like how to turn on the washer or the coffee maker. Could she be losing her mind, just like her mother did? Matthew reassures Cass that this not the and convinces Cass to talk to a doctor, who prescribes her medication. Once Cass starts taking the meds, she decides to phone the police and let them know what time she passed Jane in the forest. Now things really get strange. Cass is receiving phone calls every day, but no one is on the line. Along with her forgetfulness, Matthew is upset because she signed a contract to have a security alarm put in their house, but Cass claims she never signed anything... but her signature is right on the contract. Cass is now sure that since she phoned the police, Jane's killer is after her. Then Cass is admitted to the hospital due to an overdose of her medication. Is Cass having a breakdown, or is someone trying to make her think she is?

I really love B.A. Paris' books, and
