The plot of this book takes place in the Dark Side of London—in an area where people live side by side with demons and other unclean powers, and life follows completely different rules. The only thing that equalizes the inhabitants of this mystical part of the city with the residents of other districts is responsibility for crimes committed. And as for crimes—there are plenty of them here. However, John Taylor, a private detective specializing in cases involving “the devilry,” knows better than anyone.
