In a world where souls are currency and sin is power, a mysterious gentleman in gold-rimmed spectacles observes humanity's descent into darkness. When Detective Carl Blackwood investigates a series of brutal murders, he believes he's hunting a human killer. But he's merely a pawn in an ancient game, where each death feeds a darker purpose. As the body count rises, so does the price of survival, forcing ordinary people to commit extraordinary evils. But who is the real monster - the demon who collects the souls, or the humans willing to sacrifice others to save themselves? A dark urban fantasy that delves into the depths of human nature, exploring how far people will go when faced with their own mortality. When survival becomes the ultimate sin, redemption might be found in the most unexpected places - perhaps even in a perfectly mixed martini served by a gentleman who's seen it all before.
