Sage Adair Mysteries Books in Order

The Sage Adair Mysteries are historical mysteries set in Portland, Oregon, and the wider Pacific Northwest in the early 1900s. The series begins in 1902, when the region is booming, but the money and influence are not spread evenly. Timber companies, employers, politicians, and well-connected operators have plenty of power. Workers, immigrants, homeless people, and families living close to the edge often pay the price.

Sage Adair knows both sides of that divide. He struck it rich in the Klondike and, with his mother Mae Clemens, runs Mozart's Table, an elegant Portland restaurant. That public role lets him move among business leaders and the wealthy. Away from the restaurant, Sage works undercover for the labor movement, often using the identity of John Miner to investigate the problems that powerful people would rather leave buried.

He is not a conventional detective.

Each book gives Sage a different crisis, but the cases are linked by the same city and the same circle of allies. He investigates a timber fraud, searches for missing union organizers, faces a strike gone bad, and looks into danger surrounding President Theodore Roosevelt's Portland visit. Later stories take him into Central Oregon during a conflict between cattle ranchers and sheep herders, into the brutal world of steam laundries, and beyond the city limits.

The series is at its best when Sage has to work across social lines. He can gather gossip in fashionable rooms, then change clothes and disappear into working-class neighborhoods, rail yards, saloons, lumber camps, or picket lines. Mae is more than a restaurant partner and mother. She is a steady presence in the investigations, and the recurring cast brings practical skills, local knowledge, and a willingness to take risks.

The stakes are usually personal before they become political.

Stoner builds the mysteries around real issues from the Progressive Era, including unsafe work, strikebreaking, shanghaiing, child labor, graft, environmental exploitation, and racial injustice. The historical setting matters because it shapes what characters can safely say, where they can go, and who will be believed when something goes wrong. It also gives the cases a grounded sense of place, from muddy Portland streets to dry Central Oregon country.

Expect direct, fast-moving mysteries with a strong social conscience. The books do not treat history as distant background. They focus on the people caught inside it, especially those organizing for safer jobs, fair treatment, and a little more control over their own lives. Start with Timber Beasts for Sage's backstory and the fullest introduction to his world, then read in publication order to follow the returning characters and the changing political landscape.
