Detective stuff

I'm really big on mystery and detective stories right now, particularly really intricate mysteries that require a lot of thought before the mystery can be solved, by the reader/observer or by the characters in the story. I'm currently reading Death Note: the Los Angeles BB Murders and it's really intriguing. It's not the best-written story but it's also translated, though I'm not fond of the narration style. Regardless, the mystery is really intriguing.

The lead would probably be a smart female detective who is a very quick thinker. I'm not sure exactly what the plot would be but it would be written somewhat backwards to let all the threads tie in together.
