What are some good mystery/supernatural books/comics that involves a detective and his friends solving a mystery? Like a murder mystery or having to look for a supernatural item/monster due to an event that kick-starts the plot? Can be either standalone or multiple books with an overarching mystery.
Time Period: Set in the past, like in the 1800s or early 2000s. Can be in present day as well.
