Spring arrives in northern Virginia, and Mary "Harry" Harristeen, Susan Tucker, and their friends are busy planting flowers and trimming hedges to get St. Luke's Lutheran Church ready for a Homecoming celebration like no other. When the brewery owned by two members of the gardening committee gets robbed and Jeannie Cordle drops dead of poisoning at a charity auction, Harry suspects that the two crimes are connected. With help from her feline sidekicks, Mrs. Murphy and Pewter, as well as Tee Tucker the corgi and sweet puppy Pirate, Harry sets out to find the weed in St. Luke's garden—and in this 29th outing, after Whiskers in the Dark—they must stop a killer before he can strike again.
