Negative in Blue by Carter Brown (Rick Holman)

Hollywood trouble finds Rick Holman once again—and this time, the glamour is as dangerous as the crime.
When a stunning model turns up dead with only a mysterious blue-tinted photograph as a clue, Holman plunges into a world of jealous stars, shady photographers, and double-crosses waiting in every dark corner. Fast, witty, and packed with classic pulp charm, Negative in Blue is vintage Carter Brown at his twisty best.
