Mrs. Jeffries and the Yuletide Weddings (Mrs. Jeffries Series #26)

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.
