Nobody cares who killed a down-on-his-luck piano player...except his brother, who happens to work for the crimefighting detective Sister Mayhem. Tearing up the underworld with her network of operatives--the Order of No Mercy--Sister Mayhem will stop at nothing to catch the killer. She's a master of disguise, a genius investigator, and a force of nature, but when the trail leads to a band of dirty-dealing musicians, she might have met her match. Lead singer Sheila Venus has genius, skills, and feminine wiles to rival Sister Mayhem's. Did her dark schemes lead to murder, or was the killing played in a different key echoing from a bloody, secret past? Sister Mayhem pulls out all the stops to solve the case and catch the killer, unless she becomes the next victim first. Don't miss this thrill-a-minute crime saga by award-winning storyteller Robert Jeschonek, a master of unique and unexpected crime fiction and mysteries that really pack a punch.
