On a crisp September morning, a jogger stumbles upon an horrific scene in a London park... When forensic photographer Kate Gardener steps in for her injured supervisor, the brash American ex-pat finds herself at the scene of a truly brutal murder. The naked, castrated body of a young pharmacist has been found at the edge of Regent's Park. Gifted with acute sensitivity and a "photographic" memory, Kate is uniquely suited to capturing the details of crime scenes and seeing what others do not see. Something about this crime scene haunts her, though, and her frustration grows as the investigation proceeds. After the victim is linked to the sensational decade-old murder of a young woman, and a second equally-brutal crime scene is discovered, Kate has to agree with New Scotland Yard's Murder Squad detectives that there is a definite link between the cases. Then crime scene photos go missing—and a coworker's strange behavior takes center stage—and Kate begins to fear that the murderer may be close to the case... and about to strike again. Kate's instincts for solving crimes have always been spot-on... but finding the truth this time may be more dangerous than she could ever have imagined.
