She keeps house for Inspector Witherspoon . . . and keeps him on his toes. Everyone's awed by his Scotland Yard successes-but they don't know about his secret weapon. No matter how messy the murder or how dirty the deed, Mrs. Jeffries's polished detection skills are up to the task . . . proving that behind every great man there's a woman-and that a crimesolver's work is never done. The week before Christmas, Inspector Gerald Witherspoon's staff prepares for the long-awaited wedding of Betsy and Smythe. But when a middle-aged spinster is killed in what looks like a random crime, the Inspector suspects otherwise. With uncooperative witnesses, sulking relatives, and a second Christmas wedding, a simple investigation seems as unlikely as catching St. Nick at work.
