Big Tom took up his practice again as Sam crossed the floor. His was the only music in the place, but it was a weeknight and still early. The Penumbra wouldn’t start rocking for another couple of hours. There were a few patrons scattered about at the freestanding tables and in the alcoves along the back wall. That was fine. There were enough people to keep things friendly but not enough to crowd sensitive discussions. The club’s regulars minded their own biz.
