Bobby Davis discovers a bag of money on a job site, and what he does after becomes the undoing of everyone seated around him on the Orange Line: Marigold Winter is a thirtysomething assessing strangers on the train with perfect accuracy while lacking clarity about her own self; Lark Brooks is heading to a job interview for a position he thinks will fix all of his problems; an octogenarian is searching for someone to continue her life’s work; a young mother is contemplating a divorce; and an oblivious teenager is attempting to write a new song for his punk band.

Then Bad Bobby stands up and forces them all to face their fears, whether they’re ready to do so or not.

A MATTER OF COURSE is a multi-point-of-view butterfly effect of one man’s mental downslide. It offers a dose of mystery, a touch of romance, and a good bit of what real life throws at us.
