Seven Floors Down follows the lives of Ryder and Kendall through bouts of homicide and homelessness, beginning when Ryder gets out of jail and crashes with his alcoholic friend who, on the verge of being evicted, remains infuriated with an ex-cop who owes him thousands. Kendall is a raconteur who entertains with countless stories, often while lying supine on the floor, and Ryder decides to help his friend recover his money. But then there's an accidental killing and Ryder leaves Toronto on a bus for Vancouver where he lives in the downtown east side, goes through a job and a few women—including one with a crack habit—which of course ends badly. And then the police get involved.

Well into his forties, Derrick Rowe finds himself chasing stray women and stealing cash from the bookstore he manages. Having decided it's time to stop spinning his wheels, he's recently turned to robbing banks. Meanwhile, he bails his friend Jack Lofton out of jail, a burly fellow in an alcoholic free-fall of his own. Rowe soon enlists both Lofton and a tough young clerk at the bookstore in another heist, setting the stage for an armed bank robbery, a drive-by shooting, and further complications for all. Told from different perspectives in Clark's signature clear, concise prose, Hair-Trigger follows the various trails and exploits that lead to a violent climax involving Rowe, Lofton, the police, and several gangsters.
