The rope artist
(Book)

"Two detectives. Two identical women. One dead body— then two, then three, then four. All knotted up in Japan’s underground BDSM scene and kinbaku, a form of rope bondage which bears a complex cultural history of spirituality, torture, cleansing, and sacrifice. As Togashi, a junior member of the police force, investigates the murder of a kinbaku instructor, he finds himself unable to resist his own private transgressive desires. In contrast, Togashi’s Sherlock Holmesian colleague Hayama is morally upright to a fault, with a stalwart commitment to the truth and nearly superhuman powers of deduction. When Hayama notices a dangerous measure of darkness within Togashi, he embarks on a parallel investigation, which soon spirals out of control. Unflinching in its flayed-raw treatment of identity, violence, sexuality, power, the occult, and the divine, The Rope Artist is both viscerally painful and unexpectedly hopeful—a genre homage that shines a light on the most dangerous elements of the human psyche." --publisher's website.
