A Body under the Christmas Tree — Steve Demaree

A retired detective is getting ready to go up into his attic to retrieve the Christmas tree that he had been decorating for the last eighteen years. Before he could do that, his partner from homicide, also retired, called him to see if he was willing to go out to a tree farm to cut down a live tree for Christmas. Against his better judgment, he agreed to do that. Before the day was over a corpse was discovered under a Christmas tree and the two detectives had to go back to work to bring a murderer to justice. Like all the other books in this whodunit series, the book is full of twists and turns and humorous moments.
