For a while he behaved with the composure and astuteness which most criminals possess up to a certain point, the lack of which, after that, is generally the cause of their detection. He did not, for instance, immediately pay off his debts, but took into his house a young man as lodger, who occupied his mother’s room, and he dismissed the assistant in his shop, and did the entire serving himself. This gave the impression of economy, and at the same time he openly spoke of the great improvement in his trade, and not till a month had passed did he cash any of the bank-notes which he had found in a locked drawer in his mother’s room. Then he changed two notes of fifty pounds and paid off his creditors. At that point his astuteness and composure failed him. He opened a deposit account at a local bank with four more fifty-pound notes, instead of being patient, and increasing his balance at the savings bank pound by pound, and he got uneasy about that which he had buried deep enough for security in the back garden. Thinking to render himself safer in this regard, he ordered a cartload of slag and stone fragments and with the help of his lodger employed the summer evenings when work was over, in building a sort of rockery over the spot. Then came the chance circumstance which really set match to this dangerous train. There was a fire in the lost luggage office at King’s Cross Station (from which he ought to have claimed his mother’s property) and one of the two boxes was partially burned. The company was liable for compensation, and his mother’s name on her linen, and a letter with the Sheffield address on it, led to the arrival of a purely official and formal notice, stating that the company were prepared to consider claims. It was directed to Mrs Linkworth, and Charles Linkworth’s wife received and read it.
