Erik Grossman couldn’t have passed for a beautiful creature in a dark room during a total eclipse of the sun. A rogue scientist and self-made mad doctor in his early thirties, Erik had been banned from universities all over Europe for his unorthodox and unethical medical experiments. At the last count, Interpol had arrest warrants out for him under eleven different names. Erik had his own private gallery of Wanted posters with his face on them, the one touch of personal vanity he allowed himself. Erik’s problem was that he saw the human body as a series of fascinating but inherently flawed and inefficient mechanisms; and he couldn’t resist the urge to tinker and try to improve them. To begin with, he cut bodies open and committed terrible, ruthless surgeries on what he found there. When that didn’t work, or didn’t work well enough to satisfy him, he moved on to cybernetics and the brutal introduction of technology into living bodies. And, occasionally, vice versa.

Erik’s other problem was that he couldn’t always be bothered to find properly willing subjects. So he used stray animals and homeless people, along with drugs and machines and techniques he was forced to create in his own very private laboratories because they didn’t exist anywhere else. He had his successes and his failures, but he wasn’t nearly as efficient as he should have been in disposing of the remains. Erik was on the run, hunted across Europe by a dozen different organisations, when the Crowley Project found him and lured him to its cold bosom with the offer of well-stocked laboratories, cutting-edge technology, and more untraceable animal and human test subjects than he could shake a scalpel at. In return, of course, for his exclusive services.

Erik wasn’t cruel, as such—unlike Natasha. He didn’t care enough about his subjects to feel anything for them. They were only raw materials. For him, the end was everything.

He wasn’t much to look at. Medium height, a bit podgy, with flat blond hair and pale blue eyes. People found his presence disturbing because on some level they could sense they meant nothing to him. There was less human feeling in Erik than in many of the ghosts he pursued. He tended to slide and shuffle along, head down, as though always half-expecting to be shouted at, or struck. But when his eyes came up, they were always fierce and angry, a man rehearsing his revenges against an indifferent and ungrateful world. He did have feelings. But typically, he only wanted the things and people he couldn’t have, to justify his doing terrible things to those who denied him what he wanted. This was obvious to many people, but no-one had ever been foolish enough to tell him. It wouldn’t have been safe.
