He had not had much to worry him in his middle age; his youth had been a struggle, but he had been young and strong to bear with it, blest by a homely and affectionate wife, who struggled with him and consoled him; then had followed for more years than we care to reckon just now, the everyday life of a London shopkeeper--a life of business-making and money-making, plodding on in one groove, with little change to distract his attention, or trouble his brain. All quiet and monotonous, but possessing for John Wesden peace of mind, which, if not exactly happiness, was akin to it. And now in his old age, when every habit had been burned into him as it were, business was over, and idleness became a sore trial to him. And then after idleness came his daughter to worry him, not to mention Mattie, who worried him most of all, for reasons which we shall more closely particularize a chapter or two hence. So with these troubles bearing all at once upon a mind that had been at its ease in its stronger days, Mr. Wesden turned eccentric. Want of method rendered him fidgety, the mysteries in _his_ path, as well as Mattie's, perplexed him; he was verging upon hypochondriacism without being aware of it himself; and that suspicious nature which had been born with him, began to develop itself more, and give promise of bearing forth bitter fruit. Possibly before his concern for his daughter's health, was his concern for the shop in Great Suffolk Street, which he considered that he had neglected in leaving to the charge of a girl not eighteen years of age, and which, since the robbery, was an oppression that weighed heavily upon him. He was full of fancies concerning that shop; his mind--which unfortunately was fed by fancies at that time--began to give way somewhat when he took it in his head to think something had happened, at twelve o'clock at night, and start at once for Great Suffolk Street, as we have noticed in our preceding chapter. The ice once broken, the eccentricities of Mr. Wesden did not diminish; he had his old bed-room seen to in the house again, and surprised Mattie more than once after this by sudden appearances at untimely hours. He had a right to look after his business--did _people_ think that he had lost his interest in the shop, because he lived away from it?--did _people_ think that he was not sharp enough for business still? With these changes he became more nervous, more irritable, and less considerate; yet brightening up sometimes for weeks together, and becoming his old stolid self again, to the relief of his wife and daughter. That daughter detected the change in her father also, woke up at last to the fact that her own thoughtfulness had tended to unsettle him, and became more like her old self also--or rather, more of an actress, with the power to impersonate that self from which she had seceded.
