With "fascinating forensics and insider insights" (People), Leonard Goldberg reunites pathologist Joanna Blalock and detective Jake Sinclair in a cutting-edge novel about the mysteries of the mind-and the dangers of unraveling them. Dr. Karen Crendall's suicide didn't make sense. She was on the verge of a medical breakthrough-using brain tissue DNA to recapture aural and visual memories. Joanna Blalock and detective Jake Sinclair are convinced it was murder. But to prove their case they have to use the victim's revolutionary research-and enter the recesses of Dr. Crandall's mind-to unveil a killer hidden in memory's darkest realm.
