Detective Docherty and the Sorcerer's Game - Detective Docherty, #3

It's summer in the city of Toronto, the trees are green, the birds are singing, and among the construction and car exhaust, the Detective and his assistants are on the move. Trouble is stirring between the worlds of man and magick. Otherkin and fairy murders have gone-on unnoticed and without consequence, and while the human legal system feels it is out of their jurisdiction, the detective agency feels otherwise.
Overwhelmed with reports of fairy and otherkin washing up dead on the shores of Lake Ontario and mysterious murders happening throughout the city, the Detective and his team are feeling the heat. Are these murders linked? Who could be powerful enough to take out so many otherkin? Should they go ahead and just blame the wizards or get on with the real detective work? And anyone happen to know what a Gagnonian is? Who wrote this???
