I am perfectly satisfied with your company if you will tolerate mine.

Our friends are wise, for it is certainly a very fine morning for a walk." He quickened his pace until we had decreased the distance which divided us by about half.

Then, still keeping a hundred yards behind, we followed into Oxford Street and so down Regent Street.
Once our friends stopped and stared into a shop window, upon which Holmes did the same.

An instant afterwards he gave a little cry of satisfaction, and, following the direction of his eager eyes, I saw that a hansom cab with a man inside which had halted on the other side of the street was now proceeding slowly onward again.
"There's our man, Watson! Come along! We'll have a good look at him, if we can do no more." At that instant I was aware of a bushy black beard and a pair of piercing eyes turned upon us through the side window of the cab.
Instantly the trapdoor at the top flew up, something was screamed to the driver, and the cab flew madly off down Regent Street.
Holmes looked eagerly round for another, but no empty one was in sight.

Then he dashed in wild pursuit amid the stream of the traffic, but the start was too great, and already the cab was out of sight.
"There now!" said Holmes bitterly as he emerged panting and white with vexation from the tide of vehicles.
