Winner of the 2018 Arthur Ellis Award for Best First Crime Novel!



When her park is threatened, warden Jenny Willson takes it very personally.



Jenny Willson is a hard-edged, caustic-witted warden from Banff National Park who considers poachers and ladder-climbing bureaucrats equally repulsive and worthy of the same painful fate. Does keeping her promise to protect her park from them mean crossing lines and putting her career at risk?


When Willson discovers animals disappearing from Canada's mountain parks, she begins a complex investigation that follows a trail of deceit, distraction, and murder. With a growing list of victims, both animal and human, Willson finds herself in a race for justice that criss-crosses the Canada-U.S. border and pushes her to a place from which she might not return.

No Place for Wolverines

by Dave Butler

Published 13 October 2018
Park warden Jenny Willson is in a dangerous race for answers that could create an irreparable rift in her own organization.

When Park Warden Jenny Willson initiates a covert inquiry into a proposed ski hill in Yoho National Park, she’s quickly drawn into a web of political, environmental, and criminal intrigue that threatens to tear apart a small B.C. town. Suddenly, neighbour is pitted against neighbour, friend against friend, and family against family.


After a wolverine researcher dies in a mysterious fire, Willson forms an uneasy alliance with an RCMP corporal and an investigative journalist to expose the truth behind the project. But all is not what it seems. In a showdown involving the ski hill proponent, her own agency, and mysterious political puppeteers, Willson must decide if she’s willing to risk her career — and perhaps the lives of herself and those close to her — to reveal what lurks in the shadows.

In Rhino We Trust

by Dave Butler

Jenny Willson finds more than she bargains for when she travels to Namibia to save local wildlife from poachers.

Parks Canada warden Jenny Willson has left Canada to join an American colleague on a secondment to assist Namibian authorities trying to stem the loss of the country’s rhinos to illegal hunting. But the plan takes a dramatic turn when Willson finds herself in the crosshairs of a conspiracy involving wildlife poachers backed by a shadowy network of international buyers prepared to eliminate any obstacles in their way, including Willson and her new team.

While the Namibian assignment allows Willson to sidestep personal and professional questions that remain unanswered back home, she quickly recognizes that her decision to leave the Canadian Rockies could have deadly ramifications.
