As she was (very bad handwriting apart) a more than indifferent speller, and as Joe was a more than indifferent reader, extraordinary complications arose between them which I was always called in to solve.
The administration of mutton instead of medicine, the substitution of Tea for Joe, and the baker for bacon, were among the mildest of my own mistakes.
However, her temper was greatly improved, and she was patient.

A tremulous uncertainty of the action of all her limbs soon became a part of her regular state, and afterwards, at intervals of two or three months, she would often put her hands to her head, and would then remain for about a week at a time in some gloomy aberration of mind.

We were at a loss to find a suitable attendant for her, until a circumstance happened conveniently to relieve us.

Mr.Wopsle's great-aunt conquered a confirmed habit of living into which she had fallen, and Biddy became a part of our establishment.
It may have been about a month after my sister's reappearance in the kitchen, when Biddy came to us with a small speckled box containing the whole of her worldly effects, and became a blessing to the household.
Above all, she was a blessing to Joe, for the dear old fellow was sadly cut up by the constant contemplation of the wreck of his wife, and had been accustomed, while attending on her of an evening, to turn to me every now and then and say, with his blue eyes moistened, "Such a fine figure of a woman as she once were, Pip!" Biddy instantly taking the cleverest charge of her as though she had studied her from infancy; Joe became able in some sort to appreciate the greater quiet of his life, and to get down to the Jolly Bargemen now and then for a change that did him good.

It was characteristic of the police people that they had all more or less suspected poor Joe (though he never knew it), and that they had to a man concurred in regarding him as one of the deepest spirits they had ever encountered.
Biddy's first triumph in her new office, was to solve a difficulty that had completely vanquished me.
