Showing The Scent of Murder by Barbara Block

Robin Light was behind the fish tanks of her Syracuse pet shop when the teenager walked in the door. With her electric blue hair, corpse-white lipstick, and in-your-face nose ring, Amy Richmond wasn't the type you could forget. But her appearance paled beside the message she had for Robin, "Murphy said you'd help me."

Murphy was Robin's ex-husband who'd lived fast and died too young. And now, his 15-year-old daughter Amy was in trouble recently named the prime suspect in the sensational murder of her wealthy stepfather. Suddenly, the inveterate sleuth finds herself moving through the edgy, drug-infested world into which Amy has disappeared. Hitting up on her street connections, Robin plugs into a secret network of strippers, addicts, and runaways, where a low-life named Toon Town appears to be calling all the shots, and where Robin has to find a terrified young girl, before it's too late.
