Ten Second Staircase: a Peculiar Crimes Unit Mystery Reprint edition

It?s a crime tailor-made for the Peculiar Crimes Unit: a controversial artist is murdered and displayed as part of her own outrageous installation. No suspects, no motive, no evidence?but this time they do have an eyewitness. A twelve-year-old claims the killer was a cape-clad highwayman atop a black stallion. Whoever the killer really is, he seems intent on killing off enough minor celebrities to become one himself. As?Highwayman Fever? grips London, Bryant and May, along with the newest member of the Unit, May?s agoraphobic granddaughter, April, find themselves sorting out a case involving artistic rivalries, sleazy sex affairs, the Knights Templars, feuding street gangs, and a decades-old crime spree that split up their partnership once before?and threatens to end it again?with murder.
