+One night--it was on the twentieth of March, 1888--I was
+returning from a journey to a patient (for I had now returned to
+civil practice), when my way led me through Baker Street. As I
+passed the well-remembered door, which must always be associated
+in my mind with my wooing, and with the dark incidents of the
+Study in Scarlet, I was seized with a keen desire to see Holmes
+again, and to know how he was employing his extraordinary powers.
+His rooms were brilliantly lit, and, even as I looked up, I saw
+his tall, spare figure pass twice in a dark silhouette against
+the blind. He was pacing the room swiftly, eagerly, with his head
+sunk upon his chest and his hands clasped behind him. To me, who
+knew his every mood and habit, his attitude and manner told their
+own story. He was at work again. He had risen out of his
+drug-created dreams and was hot upon the scent of some new
+problem. I rang the bell and was shown up to the chamber which
+had formerly been in part my own.
