"You forget that I know nothing about it."
"I shall just have time to tell you the facts of the case before we get to Lee. It seems absurdly simple, and yet, somehow I can get nothing to go upon. There's plenty of thread, no doubt, but I can't get the end of it into my hand. Now, I'll state the case clearly and concisely to you, Watson, and maybe you can see a spark where all is dark to me."

Now, if you are well up in your London, you will know that the office of the company is in Fresno Street, which branches out of Upper Swandam Lane, where you found me to-night. Mrs. St. Clair had her lunch, started for the City, did some shopping, proceeded to the company's office, got her packet, and found herself at exactly 4:35 walking through Swandam Lane on her way back to the station.
