Even in the remote fur trading section of Canada, Sergeant Douglas Renfrew finds a lady in distress.

Larkin's partner, along with another Mountie, are found murdered: word came down from the remote region of the Pacific Northwest from Dr. Howe, who resides there.

But after finding old man Larkin, and arresting him in the name of the Crown, Renfrew hears his story and suspect's Kay's father is innocent of the charges.

Pierre, an employee of a trading post up north, is suspect until Dr. Howe's guilt is revealed.

The motive was theft and greed that resulted in a murder neither party wanted to be involved, then attempted to cover their tracks.
