Thin Disguise

On her first day in Las Vegas, Olivia Wright arrives to apply for a job writing the memoirs of fading movie star Margot Farr, famous for her carousel of husbands and her roller coaster weight. When Margot is murdered and Olivia discovers the detective is her former lover, Mace Emerick, she agrees to be the homicide department's secret witness inside the investigation. Plenty of suspects stood to gain by Margot's death, but when Olivia is exposed to the press as a witness and Mace is fired, the two of them are on their own to solve the crime.
