Death Note Another Note: The Los Angeles BB Murder Cases

Another Note follows FBI Agent Naomi Misora as she is enlisted by the Great Detective L to help him solve a series of perplexing and brutal murders in Los Angeles, each with a Wara Ningyo (a Japanese straw doll) left at the crime. She is soon joined in her investigation by a mysterious "unprivate" detective called Ryuzaki.
