Thank God!" he shouted. "Come here quickly!" "Why?" I asked. "Come on, man, we need you!" And so I helped Godfrey Norton to marry Irene Adler. They needed a witness, and a servant from the street was better than nobody.' 'So she's married him! What shall we do now?' I asked. 'Well, tonight, my dear Watson, I need your help. Will you do what I ask? Without questions?' 'Of.course, Holmes, if you think that it's important,' I answered. 'Later, we'll go to Briony Lodge. Irene Adler, or Irene Norton, will arrive home at seven o'clock, and she will ask me to go into the house. You must wait outside near the sitting-room window, and when it opens, watch me inside. When I hold up my hand, throw this thing into the room and shout "Fire!"' I took the small thing out of his hand. 'What is it, Holmes?' I asked. 'It's a smoke-stick. The room will very quickly be full of smoke. After that, wait for me at the corner of the street.' 'Right, I'll do what you want,' I said.
