The Big Both Ways by John Straley is a mystery/adventure set in the Pacific Northwest in 1935; fictional characters set in the backdrop of actual events in the historic violent struggle to form labor unions (for example, the Pinkertons appear as strike-breakers).
Slip Wilson left his parents' farm in the Dust Bowl to find work. Big, strong, and hard-working, he did well as a logger in the Pacific Northwest, saving a nest egg for his future. He dreams of owning his own property and business. When his best friend and fellow logger dies in a logging accident, Slip decides it's time to go build his dream. Hitchhiking his way to Seattle, he catches a ride with Ellie Hobbes. Once he realizes she's involved in a crime, he wants to go his own way - but she tricks him into helping her.
In Seattle, Slip meets Ellie's young niece Annabelle and her pet bird, Buddy. Slip joins Ellie at a labor union committee meeting, where violence erupts. Once again, he attempts to go it alone, this time in a dory; Ellie and Annabelle catch up just as he departs. Together, they flee the criminals that are pursuing Ellie (and now Slip), tackling the Puget Sound in a tiny boat.
They soon learn the 'Big Both Ways' is the nickname for the Inside Passage, whose flow changes direction with the tide. Slip, Ellie and Annabelle are no match for the fierce current in a small dory. They accept help from a man piloting a larger boat - until he tries to kidnap Annabelle. Slip and Ellie work for a time in a cannery - where hazardous conditions have tragic consequences for Ellie.
In a parallel plot, a detective from Seattle also travels north, to solve the crimes Ellie and her anarchist cohorts committed back in Seattle.
The working conditions illustrate the dire need at the time for labor reform, however the criminal acts of union organizers reveal dark motives. Slip and Ellie's journey runs the gamut from gritty and depressing, to gripping and exciting. They finally reach Alaska, where the detective catches up to them, in a difficult to understand labor standoff, followed by a surprising conclusion.
