A brutal murder of a well-known and respected senior physician at Tempe General shocks the community. But it's just the beginning—a violent avenger stalks the hospital's corridors and more people may be on his kill list.

After AJ Docker fails to resuscitate the first victim, he is determined to prevent further violence. With his friend Dirk at his side and Banshee guarding his back, Doc hunts for the killer. His inquiries uncover the hospital's dark, sordid past and lead him to seek files rumored to contain information that might identify the killer. No one knows whether the files actually exist, and it's unclear who is helping Doc and who might be helping the killer.

Phantom Files once again showcases Gerlacher's medical knowledge skillfully integrated with a complex plot full of twists and turns. The pace is fast, the action intense, and the characters unforgettable—as readers have come to expect from this bestselling series.
