Keeping someone alive can be the cruelest thing of all.

In Woonsocket, Rhode Island, a beloved doctor is found dead outside a hospital. He’s been stabbed, and a medical tube has been jammed down his throat. Maya Frost, now officially an FBI special agent with the Behavioral Analysis Unit, is sent to investigate. The doctor was not the first, nor is he the last, and Maya discovers that she’s dealing with a serial killer with a grudge against those who heal the sick.

Partnered once again with veteran profiler Devon Lynch, Maya must navigate the disturbing underbelly of the medical world to track down a monster who believes death is as much a gift as life. And all the while Maya is carrying a piece of evidence from a previous case she can't explain and hasn't reported. Before it’s all over, Maya must go to the one place she’s been avoiding for a decade and can’t avoid any longer.

Dark, disturbing, and impossible to put down, Who the Devil Keeps is a gripping FBI thriller packed with shocking twists, unforgettable characters, and a killer whose motives are more terrifying than his crimes. Perfect for fans of Gillian Flynn, Karen Slaughter, Lisa Regan, and Melinda Leigh.
