Nightshade

Deadly nightshade -- the poison plant par excellenc-- and in historic Quebec City at an important scientific conference concerning the genetic manipulation of trees it means murder!

Police, RCMP, and a mysterious FBI agent from Washington converge on the scene. But the sharpest eye belongs to Sam Montcalm, a despised "bedroom snooper" from Ottawa whose primary concern is to clear a First Nations activist of the crime. Sam is middle-aged, tough, and sophisticated, yet he's also a lone wolf who feels displaced nearly everywhere, and his relations with his colleagues, the police -- and with women -- are always complicated. "You're a psychic wound without a health card," a friend comments.

The story moves to its surprising climax as Montcalm follows the trail of murder back to Canada's capital and into the Gatineau Hills, his deep sense of cynicism about human nature confirmed as he closes in on the killer and struggles to come to terms with himself.
