Part Two

As we walked rapidly down Howe Street I glanced back at the building which we had left. There, dimly outlined at the top window, I could see the shadow of a head, a woman's head, gazing tensely, rigidly, out into the night, waiting with breathless suspense for the renewal of that interrupted message. At the doorway of the Howe Street flats a man, muffled in a cravat and greatcoat, was leaning against the railing. He started as the hall-light fell upon our faces.

“Holmes!” he cried.

“Why, Gregson!” said my companion as he shook hands with the Scotland Yard detective. “Journeys end with lovers' meetings. What brings you here?”

“The same reasons that bring you, I expect,” said Gregson. “How you got on to it I can't imagine.”

“Different threads, but leading up to the same tangle. I've been taking the signals.”

“Signals?”

“Yes, from that window. They broke off in the middle. We came over to see the reason. But since it is safe in your hands I see no object in continuing this business.”

“Wait a bit!” cried Gregson eagerly. “I'll do you this justice, Mr. Holmes, that I was never in a case yet that I didn't feel stronger for having you on my side. There's only the one exit to these flats, so we have him safe.”
