Death Note, Vol. 10

In this volume, Light Yagami finds a Death Note and decides to use it to kill criminals. L, a detective who is known for his skills in tracking down criminals, is sent to investigate.

Light Yagami, a straight-A student with great prospects, is bored out of his mind, but that all changes when he finds a Death Note--a notebook dropped by a rogue Shinigami death god--and when criminals begin dropping dead, the authorities send the legendary detective L to track down the killer.
