"DS Jamie Brooke enlists the help of clairvoyant Blake Daniel to follow a macabre trail of murder, grave robbery, and genetic modification..." and finds out she's a lying-ass fraud? Just a suggestion. Have you noticed the psychics in these stories (books and movies) never offer a damned thing that really helps - only the vaguest of clues so the author can spin the story on and on. It would be more of a challenge if the psychic nailed the perp down to name and address and the author still managed to find a good story. Why don't I do that? Maybe I will.
But no psychic ever solved a murder. Ever. Period. Cops do that. Not psychics. Not bakers. Not librarians. Not café owners. Not cupcake shop owners. Not ladies' knitting circles. Not bookshop owners. Cops. Hard-working cops. That's it.
