Christmas at the Puzzle Store

It's Holiday Season. In the spirit of classic Science Fiction, Christmas at the Puzzle Store takes you to places strange, but recognizable. Mostly. Whether it's chasing a fugitive or fleeing the ghosts of the past, everyone ends up at the Puzzle Store as you'll see in these five original stories, first published here: The Ghost of Christmas Maybe On the Feast of Stephen Christmas on the Village Green How Santa Saved Christmas In Royal David's City Mac's having a sale.
Be careful which puzzles you look at, because you may never see a jigsaw puzzle the same way again.
