He guessed that a man who was risking so much as the emissary appointed by Melun would take good care to provide himself with sure and certain means of escape. It was doubtful if he would trust to the swiftness of his feet, to the chance of catching a passing omnibus, or to losing himself in the underground. In all likelihood, though he might walk to the actual place of appointment, he would probably drive to some neighbouring spot in a motor-car. It was upon this very reasonable assumption that Westerham based his plans. The difficulty was, as he knew full well, that a score of little streets and alleys led into St. Paul's churchyard, and any and all of these would be open to Melun's ambassador. Westerham did his best to place himself in the position of the man whom Melun was sending to the cathedral steps. And arguing the matter out from this point of view, he came to the conclusion that he would drive to Queen Victoria Street or Newgate Street by car, and then proceed to the meeting-place on foot. He ruled the junction of Newgate Street and Cheapside out of court, as not offering sufficient opportunities of shelter. That the man would choose the point at which Queen Victoria Street ran into Cannon Street was equally unlikely. That left only one other route of escape—namely, the open thoroughfare of Ludgate Hill. This also Westerham set aside as being unnecessary to consider. That any man should attempt to escape down that broad street at a time of night when it would be almost empty was too ridiculous to contemplate. He decided, therefore, that two motor-cars would be sufficient for his purpose, and having ordered them, he sent for Lowther and Mendip, to whom he explained his plans. He himself, he said, intended to go to St. Paul's by omnibus, so as to reach the cathedral as nearly as possible on the stroke of nine. By that time Mendip was to be in waiting in Queen Victoria Street, almost opposite the headquarters of the Salvation Army. Lowther he instructed to wait at the corner of Angel Lane. For though the man might choose one of the four alleys leading from the churchyard up to Newgate Street, he must reach the main thoroughfare either just to the east, or just to the west, of Angel Lane. Whether the man would be so bold as to adopt either of the courses which Westerham decided that he himself would choose was an open question. It was a risk, however, which had to be taken, be the consequences what they might. Westerham saw that whatever line of country the man might take at the close of the interview, the task of following his steps would devolve upon himself. He could trust no man on that mission, though he saw that he would at the best make but a poor shadower. His bulk was much against him. Sir Paul, however, had an alternative scheme in mind should it fall out that the man discovered he was followed. But of this he said nothing to the others.
