The safes while on the line _en route_ between London and Folkestone were in the guard's van. This was an important step, and they might easily be robbed some day when Burgess was the guard, provided only that they could be opened. The next step was to get impressions and fabricate false keys. A new accomplice was now needed within the company's establishment, and Pierce looked about long before he found the right person. At last he decided to enlist one Tester, a clerk in the traffic department, whom he thought would prove a likely tool. The four waited patiently for their opportunity, which came when the safes were sent to Chubbs' to be repaired; and Chubbs sent them back, but only with one key, in such a way that Tester had possession of this key for a time. He lent it to Agar for a brief space, who promptly took an impression on wax. But the safes had a double lock; the difficulty was to get a copy of the second key. This was at length effected by Agar and Pierce. After hanging about the Folkestone office for some time, they saw at last that the key was kept in a certain cupboard. Still watching and waiting for the first chance, they seized it when the clerks left the office empty for a moment. Pierce boldly stepped in, found the cupboard unlocked; he removed the key, handed it to Agar outside, who quickly took the wax impression, handed it back to Pierce; Pierce replaced it, left the office, and the thing was done. After this nothing remained but to wait for some occasion when the amount transmitted would be sufficient to justify the risks of robbery. It was Tester's business, who had access to the railway company's books, to watch for this. Meanwhile the others completed their preparations with the utmost care. A weight of shot was bought and stowed in carpet bags ready to replace exactly the abstracted gold. Courier bags were bought to carry the "stuff" slung over the shoulders; and last, but not least, Agar frequently travelled up and down the line to test the false keys he had manufactured with Pierce's assistance. Burgess admitted him into the guard's van, where he fitted and filed the keys till they worked easily and satisfactorily in the locks of the safe. One night Tester whispered to Agar and Pierce, "All right," as they cautiously lounged about London Bridge. The thieves took first-class tickets, handed their bags full of shot to the porters, who placed them in the guard's van. Just as the train was starting Agar slipped into the van with Burgess, and Pierce got into a first-class carriage. Agar at once got to work on the first safe, opened it, took out and broke into the bullion box, removed the gold, substituted the shot from a carpet bag, re-fastened and re-sealed the bullion box, and replaced it in the safe. At Redhill Tester met the train and relieved the thieves of a portion of the stolen gold. At the same station Pierce joined Agar in the guard's van, and there were now three to carry on the robbery. The two remaining
