Some time in 1862 a large deficiency in the stock of bank paper unglazed was discovered at the mills. Soon afterwards the inspectors of bank-notes at the Bank of England detected the presentation at the bank of spurious notes on genuine paper. The two facts taken in conjunction led to the employment of the police, and the offer of a reward of £1500 for the detection of the offenders. By this time Brown alone had stolen three or four hundred sheets, each containing two notes, many of the sheets suitable for engraving any kind of note from £1000 downwards. The amount of Brewer's abstractions (who was eventually acquitted) was never exactly estimated. Suspicion appears to have rested on Brown, who had left Laverstock, and he was soon approached by the police. Almost directly he was questioned he made a clean breast of the whole affair. The next step was to take the principals, and under such circumstances as would insure their conviction. A watch was set on Burnett, who was followed to the shop of one Buncher, a butcher in Strutton Ground. Buncher was then tracked to North Kent Terrace, New Cross, where a Mr. and Mrs. Campbell resided, with whom he did business in exchanging the false notes. The police officers now taxed Mrs. Campbell with complicity, and frightened her into collusion. With her assistance on a certain day a couple of bricks were taken out of the wall dividing her front and back parlours; the officers ensconced themselves in the latter, and waited for Buncher's expected visit. He came to complete a sale of forged notes, and he wanted a couple of hundred pounds for what he had. Mrs. Campbell offered him less, and there was an altercation, in the course of which Buncher became very violent, and at length, after using much intemperate language, he left the place in a huff. In the course of his remarks, however, he said, "I am the man that has got all the bank paper; I have £30,000 now, and the Bank of England cannot stop it." This was all the police wanted to know.
