A Bite of Rope

An ex-soldier, Arthur "Kuhn" Conrad, now a debt collector of sorts for a corrupt company, can't sleep one night, and as he's walking the streets, sees a coworker - on a whim, he follows, and ends up in an underground club. The older man, Ignatius Kasovitz, likes to tie people up, it seems, and Kuhn finds he wants to try being tied up, if it's Kasovitz doing the tying. Set in London, circa 1953, in my Magic Beholden universe, readable as standalone.
