Sometimes, the police aren't the best suited to solve a crime. Depending on the case, you may find that a retired magician, a schoolteacher, a Broadway producer, or a nun have the necessary skills to suss out a killer. Or, in other cases, a blind veteran, or a publisher, or a hard-drinking attorney, or a mostly-sober attorney... or, indeed, any sort of detective you could think of might be able to best the professionals when it comes to comprehending strange and puzzling murders.
