"I am made of this." In a Victorian mechanical and eldritch London, a black arts surgeon is ripping out the bones and organs of healthy poor folk to transplant into the afflicted bodies of the wealthy. Anti-vivisectionists battle with medical doctors, medical doctors condemn supernatural practitioners, and amidst it all the Bone Stealer hunts for his most elusive prize yet: the skeleton of a woman over six feet tall. Secret Commission agents Art, the artificial ghost, and Jim Dastard, the animated skull, rush to stop him before another woman dies. And Art, only six days living after being resurrected to serve the Secret Commission, might be that woman.
