Unwilling to accept their defeat, the two men were ransacking the desks afresh when they heard the front door open, but, supposing Brodie to be at his post, paid no attention. They were about to leave the room to prosecute their investigation of the premises when they heard some one come hastily down the stairs, “which made them stop or they must have met him.” Upon this Brown whispered, “Here must be treachery; get out your pistols and cock them!” They then heard the front door close with a crash. Perceiving that something was wrong, they now hastened into the hall, when, to their amazement, they found that the Deacon had vanished, and, on opening the door, that Ainslie also had disappeared. Cursing their ill luck and the defection of their companions, the puzzled burglars hurried through the court into the Canongate; and, quite at sea as to what had happened, made the best of their way to Smith’s house, leaving behind them in the office the heavy coulter and the spur which was designed to mislead the discoverers of the robbery. We must now return to Ainslie, whom we left on the watch behind the railings. A servant girl, returning from a message to her master’s house in the court, saw him looking over the wall, and, “judging him to be a light or suspicious person”--in which diagnosis she was not far wrong--sought safety within doors. He had not been long at his post when the silence of the court was broken by the sound of a man running into it from the street, and Ainslie, peering through the railings, was alarmed to see him go in at the open door of the Excise Office. At the very moment of his entrance another man rushed from the doorway and fled at full speed up the court; and before Ainslie could recover from his surprise at this unlooked-for situation, a third man, as he supposed, came immediately out of the office and also disappeared towards the Canongate after the other. The scanty oil lamps with which in those days the city was “illuminated” after nightfall served but as feeble foils to the surrounding darkness, and to Ainslie, in the dimly-lighted court, friend and foe were equally indistinguishable. These mysterious and unlooked-for doings proved too much for the watcher’s nerve; so, having hastily given the agreed-on signal of retreat by three blasts upon his whistle, he, too, made for the entry, and, turning down St. John’s Street, came through the gardens of the Canongate to the back of the Excise Office. Finding no trace of his associates there, Ainslie in his turn repaired to Smith’s.
