Liz Ryerson believes that Hillcrest Village, her Toronto neighbourhood, is quaint and quiet, but stumbling over a corpse while walking her dog dissolves that illusion for good. When she realizes that she actually knew the dead man, a real estate broker who appraised the building she co-owns with her philandering ex-husband, she becomes obsessed with solving the crime. The more instability is revealed in her life, the more she needs to find out who killed James Scott - and why. Retired Classics professor Maxime Bertrand is delighted to play Watson to her Holmes. For Liz, the investigation is a way of asserting control in a world she no longer recognizes. It is also a means of proving to herself and her children she is not in retreat from life but can grow and change. For Maxime, it's a way of becoming re-engaged in life after his wife's death. Neither of them anticipates the possibility of real danger, despite police warning them to stop meddling in criminal matters.
