From author Tony Berryman comes a compelling, immersive story of a massage therapist whose brush with a serial killer nurse catapults him into a fight for his patients' lives.

How does he convince them of murders only he can see?

Jackson sees patterns – the sway of trees, the flow of traffic, the design of the human body. It makes him a brilliant massage therapist. It also once landed him in a psych ward. Now he's seeing a pattern behind his elderly patients' deaths.

Nurse Wendy loves her secret calling. She knows a hundred ways to move her patients beyond their pain, forever. She's never been caught: Rule Three says When They Suspect, Move West.

Jackson's friends think he's slipping. The police don't believe him. But he won't sit on his hands while more patients die.

Wendy is horrified that someone knows about her secret work in the night. But she will never stop. And she's in Vancouver, all the way West. There's nowhere left to run.

As their paths spiral closer, neither can let the other go. Jackson will have to let the patterns take him again, learn to use them as a weapon – or lose everything to The Night Nurse.

Fans of Riley Sager and Meg Gardiner will love this gripping page-turner of a psychological thriller.
