author
A little-known writer whose surviving work carries the feel of lived experience, with wilderness danger, loyalty, and quiet toughness at its heart. The story most clearly linked to this name, Jim, centers on a former Canadian Mounted Police officer and his devoted dog.

by A. A. Strachan
Very little biographical information about this author could be firmly confirmed from the sources I found. Project Gutenberg lists A. A. Strachan as the author of Jim, originally published in 1927.
That story is presented there as a narrative about a former officer of the Canadian Mounted Police and his dog, Jim, and is described as drawing on the author's own experiences and observations while homesteading in Canada. Because reliable background material is scarce, it seems safest to remember A. A. Strachan chiefly through this rugged, heartfelt piece of writing rather than through a detailed life story.
I wasn't able to verify further personal details such as full name, birth and death dates, or a standard biographical profile from strong public sources.
