Death Note

the long version

There's a serial killer loose in Los Angeles and the local authorities need help fast. For some reason the killer has been leaving a string of maddeningly arcane clues at each crime scene. Each of these clues, it seems, is an indecipherable roadmap to the next murder. Onto the scene comes L, the mysterious super-sleuth. Despite his peculiar working habits, he's never shown his face in public—but this time, he needs help. Enlisting the services of an FBI agent named Naomi Misora, L starts snooping around the City of Angels. It soon becomes apparent that the killing spree is a psychotic riddle designed to specifically engage L in a battle of wits. Stuck in the middle between killer and investigator, it's up to Misora to navigate both the dead bodies and the egos to solve the Los Angeles Murder Cases.
