Velvet Sapphire - M L Hamilton - Bog

No one solves cases like San Francisco detectives, Peyton Brooks and her partner, Marco D'Angelo, but when a young Mexican folk singer, Ynes Linares, is found strangled with her own pearls, compiling a list of suspects that wanted to harm her is easier than figuring out who didn't. Everyone wanted a piece of the Velvet Sapphire, but someone wanted everything.
A Peyton Brooks Homicide follows San Francisco's dynamic crime-fighting duo, Peyton Brooks and Marco D'Angelo, through their early cases in the Homicide Division.
