Here's the blurb:
February 1863, and the newly opened Metropolitan Railway is the toast of London. Among the travellers tonight are the vampire, Lord Underwood, and his guardian, Ben Flinch. But they aren't travelling alone, for Underwood and Flinch have been discovered by a group intent on their destruction.
Disturbing the Devil is a journey into the smoky depths of the Victorian Underground; a stand-alone short story in the Underwood and Flinch universe, written by four-time Parsec Award-winning author, Mike Bennett. Expect blood.
