"Brennan (Loose Lips) impresses with this atmospheric whodunit set against the backdrop of Jack the Ripper's killing spree in 1888 London. Rather than the mean streets of Whitechapel, however, Brennan focuses on "the golden age of the gentleman's club," the most notorious of which is Sizar's, an establishment whose members are "soilingly, ruinously ungentlemanly" in their sexual proclivities. ... Brennan's reveals, when they come, are plenty shocking, but the narrative's main strength is its vivid portrayal of a segment of Victorian society rarely depicted in mysteries. This illuminates a dark corner of British history, with grimly satisfying results." - Publishers Weekly

"Brennan has constructed an immersive puzzle, one that delights in shattering Victorian facades of class and propriety with sex and blood. ... a fascinating look into the strange, lost world [of] gentleman's clubs and the young men ensnared in their customs.

A rich, dark mystery set in repressed 19th-century London." - Kirkus Reviews
