YMMV / Mr. Monk and the Two Assistants

• Complete Monster: Ian Ludlow is a narcissistic crime novelist who gets "inspiration" for his books by befriending his fans, murdering them, then participating in the ensuing investigations so as to frame "the least likely suspect" for the crimes. Ludlow has killed at least five people over the years, always pinning the murders on total innocents and getting them locked away, and continues his spree in the present as he kills another fan by bashing her skull in. After murdering another man by ripping him apart while drowning him, Ludlow tries to frame Monk's closest friends and assistants, Sharona Fleming and Natalie Teeger, as the killers just to torment Monk and make a more interesting "twist" for the book he plans to write.
