Quote from : Dust and Shadow: An Account of the Ripper Killings by Dr. John H. Watson Book

My friend opened a small box which Lestrade had produced. Inside lay a beautiful silver cigarette case monogrammed with Holmes's initials, underneath which ran the words, "With the Respects of Scotland Yard, November 1888." Sherlock Holmes sat with his lips parted, but no sound emerged. "Thank you," he managed at length.
