James Wainwright always considered himself a working-class engineer playing at detective, never taking the vocation for more than an idle hobby and opportunity to test some of his steampunk inventions. His investigations have always been more of a means of humoring his business partner, idle toff Alton Bartleby. That was before his adopted daughter Xin Yan was taken. Never comfortable in social situations, James finds himself tracking his daughter's kidnappers from London's Limehouse to the gritty streets of Hong Kong, down paths where his mechanical know-how won't serve him. Searching a foreign land, he'll find that his greatest challenges aren't those who have taken from him what is most dear, but letting go of his most treasured preconceptions about the world.
