Gaudy Shadows [EPUB ebook] 

Tileman could make our fantasies come true — create reality from your dreams — for a very high fee. Catering to the desires of London’s most powerful — and decadent — figures, Tileman had top-level connections to guarantee him protection and influence. But he had killed Laird Walker’s best friend — and Walker, the dead man’s sister, and a bizarre nightclub entertainer began a private war on Tileman…a war whose final battle was unimaginable horror.
