Books in the Sam Shovel Mysteries series

Sam Shovel only comes to life for twelve days a year at Christmastime, and this year, he's in time to solve a murder mystery at the North Pole. O. Tannenbaum-the world's largest supplier of Christmas trees-has been murdered, and although Nick and Nora Claus are too busy to solve the mystery, Sam has enough time on his branchy hands to take a stab at it. Woven with enough Christmas references to choke a reindeer, find out if he succeeds in Death of a Christmas Tree Salesman.
