Detective Jane Rizzoli and Forensic Scientist Maura Isles are back together, and they must go deep into the wild to find the killer! When Boston Homicide Detective Jane Rizzoli and Forensic Scientist Maura Isles arrive at the crime scene, they discover that the murder appears to have been carried out by a ferocious beast, since there are claw marks left on the corpse. But only the unkind hands of man could have dealt with the famous hunter and taxidermist Leon Gott, brutally hung like the heads of once proud animals adorning his walls. Could Gott have unwittingly awakened the most dangerous predator he has ever hunted? Maura fears this is not the killer's first or last victim. Linking the crime to a series of unsolved murders in desolate forests across the country, she wonders if the answer lies in a remote corner of Africa. Six years ago, a group of tourists on safari fell victim to a killer. Lost deep in the Botswana bush, with no means of communication and only a guide's rifle for protection, terrified tourists desperately hoped for rescue before their worst instincts or the wild animals lurking in the darkness killed them. But the deadly predator was already among them, and within a week he was gone, killing all but one. Now this killer has chosen Boston for his new hunt, and Rizzoli and Isles must find a way to lure him out of the shadows and into his cage. Even if this means providing him with a bait that the hunter cannot refuse: the victim who was able to elude him.
