When 10-year old Emilie and her family move to Knife Alley they find themselves quickly tangled up in the neighbourhood's long history of murder. Even though suspects seem to lurk around every corner, the police are no closer to solving the murders than they were 20 years ago. But when Emilie teams up with her neighbourhood friend, Christian, new clues and suspects come to light. Whether it's the kebab man with his sharp knives, the hairdresser with her sharp scissors or the gardener with his bloody spade, Emilie and Christian will not rest until the Knife Alley Murderer is off the streets and behind bars.
