The Shooting Script (Diagnosis Murder #3)
Produced by Lee Goldberg

At his neighbor's Malibu beach house, Dr. Mark Sloan discovers the bullet-riddled bodies of an aspiring actress and Rick Kershaw, a Hollywood mega-producer.

This is another fun outing from Goldberg. He happily weaves the characters together, and (ala Star Trek novels) cherry picks details from years of DM episodes. A good yarn that (at least to this fan) rings true to the characters and series.
