Von Beilstein meanwhile sped along down the Haymarket and Pall Mall to Whitehall. The clock on the stone tower of the Horse Guards showed it was one o'clock, and, with apparently aimless purpose, he lounged about on the broad pavement outside Old Scotland Yard, immediately opposite the dark façade of the Admiralty. His hawk's eye carefully scrutinised every single person of the busy throng entering or leaving the building. There was great activity at the naval headquarters, and the courtyard was crowded with persons hurrying in and out. Presently, after a short but vigilant watch, he turned quickly so as to be unobserved, and moved slowly away. The cause of this sudden manoeuvre was the appearance of a well-dressed, dark-bearded man of about forty, having the appearance of a naval officer in mufti, who emerged hastily from the building with a handbag in his hand, and crossed the courtyard to the kerb, where he stood looking up and down the thoroughfare. "My man!" exclaimed von Beilstein, under his breath. "He wants a cab. I wonder where he's going?" Five minutes later the naval officer was in a hansom, driving towards Westminster Bridge, while, at a little distance behind, the Tsar's agent was following in another conveyance. Once on the trail, the Count never left his quarry. Crossing the bridge, they drove on rapidly through the crowded, turbulent streets of South London to the Elephant and Castle, and thence down the Old Kent Road to the New Cross Station of the South-Eastern Railway. As a protest against the action of the Government, and in order to prevent the enemy from establishing direct communication with London in case of British reverses, the lines from the metropolis to the south had been wrecked by the Anarchists. On the Chatham and Dover Railway, Penge tunnel had been blown up, on the Brighton line two bridges near Croydon had been similarly treated, and on the South-Eastern four bridges in Rotherhithe and Bermondsey had been broken up and rendered impassable by dynamite, while at Haysden, outside Tunbridge, the rails had also been torn up for a considerable distance. Therefore traffic to the south from London termini had been suspended, and the few persons travelling were compelled to take train at the stations in the remoter southern suburbs.
