Meg's running Caerphilly's Helping Hands for the Holidays project, in which neighbors help each other with things they can't do and can't afford to have done. Her hopes for a relatively peaceful (if busy) Christmas vanish when someone murders Harvey the Hoarder, whose house the Helping Hands were decluttering. Was there any truth to the rumor that he had something valuable hidden beneath all his junk? Was one of his friends, neighbors, or relatives greedy enough to murder him for the rumored treasure? And what about the magpie that has been bringing her family bits of tinsel and costume jewelry - does the bird's latest gift hold a clue to solving the crime?
