Joe Trace - in his fifties, door-to-door salesman of Cleopatra beauty products, erstwhile devoted husband - shoots dead his lover of three months, the impetuous, eighteen-year-old Dorcas.

At the funeral, his determined, hard-working wife, Violet, who is given to stumbling into dark mental cracks, tries with a knife to disfigure the corpse. Passionate and profound, Jazz brings us back and forth in time, in a narrative assembled from the hopes, fears and realities of black urban life.
