Summertime demands a really good, grisly mystery, and John Moss, in his [second] novel featuring Toronto detectives Miranda Quin and David Morgan, delivers the goods ... The plot is really solid here, but it's also fun to follow the cops along the byways of Toronto and then up to Georgian Bay. Grave Doubts is a great weekend-at-the-cottage novel.
Globe & Mail, The
... John Moss has produced an elliptical dance of words ... a couple of hundred pages of puzzlement, suspicion, illumination and confusion that take Quin and Morgan all over the Southern map ... For those willing to suspend their disbelief from very high rafters, however, and who are intrigued by slippery depictions of shifting relationships, radical demonstrations of loyalties and disloyalties, and lots of interesting allusions and bits of ancillary information, it has a kind of hypnotic delight.
London Free Press, The
Quin and Morgan are as quirky and dynamic duo as there is out there fighting crime, exploring life and spinning solutions to life's mysteries ... Grave Doubts. is writing that moves the mystery novel beyond the often trite label of genre fiction into crafted storytelling that delves into the energy and desperation behind actions that can both define and destroy lives.
Hamilton Spectator, The
The story, enhanced by clever dialogue and rich prose, climaxes in a dramatic underwater rescue worthy of any thriller.
