“What I expected to see.”

“Why did you beat the pavement?”

“My dear doctor, this is a time for observation, not for talk. We are spies in an enemy’s country. We know something of Saxe-Coburg Square. Let us now explore the parts which lie behind it.”

The road in which we found ourselves as we turned round the corner from the retired Saxe-Coburg Square presented as great a contrast to it as the front of a picture does to the back. It was one of the main arteries which conveyed the traffic of the City to the north and west. The roadway was blocked with the immense stream of commerce flowing in a double tide inward and outward, while the footpaths were black with the hurrying swarm of pedestrians. It was difficult to realise as we looked at the line of fine shops and stately business premises that they really abutted on the other side upon the faded and stagnant square which we had just quitted.
