Everyone knows Dr. Watson is Sherlock Holmes' right-hand man -- so when he goes missing, it's a shock. Even Sherlock hasn't the slightest clue as to where he could be. Enola is intrigued, but weary; she's still hiding -- and getting involved could be disastrous. But when a bizarre bouquet shows up at the Watson residence, full of convolvulus, hawthorn, and white poppies, Enola must act. She dons her most discerning disguise yet to find the sender -- and quickly, for Enola knows the blossoms symbolize death!
