Suicide or murder? Only the graphologist knows for sure in this dynamite debut, the first in a new series, from forensic handwriting expert Lowe (Handwriting of the Famous and Infamous
). When celebrity publicist Lindsey Alexander drowns in her hot tub at her L.A. penthouse apartment, Lindsey's business manager, Ivan Novak, hires handwriting analyst Claudia Rose to look into the authenticity of the block-printed note left at the scene. Ivan believes it was penned by a murderer, not a suicide victim. Claudia, who was once Lindsey's friend before being alienated by her pathologically malicious behavior, isn't surprised to learn that Lindsey liked to blackmail her famous clients by threatening to tarnish rather than shine their images. When hunky LAPD detective Joel Jovanic enters the investigation, the "grapho lady" and the cop make a hot team, in and out of the sheets. The author's large nonfiction fan base augurs well for the series. Author tour. (Mar.)
