'I don't know how. I have only speculated on the coincidence; I have not tried to account for it. I feel sure he will return. When he does, dear John, let me tell him that I have at last spoken to you, and let me bring you together. He will certainly help us to a new livelihood. His entreaty was that he might do something to smooth my life and yours; and I gave him my promise that if we ever wanted a friend, I would remember him.'

'Then his name was to be no secret, 'Harriet,' said her brother, who had listened with close attention, 'describe this gentleman to me. I surely ought to know one who knows me so well.'

His sister painted, as vividly as she could, the features, stature, and dress of her visitor; but John Carker, either from having no knowledge of the original, or from some fault in her description, or from some abstraction of his thoughts as he walked to and fro, pondering, could not recognise the portrait she presented to him.

However, it was agreed between them that he should see the original when he next appeared. This concluded, the sister applied herself, with a less anxious breast, to her domestic occupations; and the grey-haired man, late Junior of Dombey's, devoted the first day of his unwonted liberty to working in the garden.

It was quite late at night, and the brother was reading aloud while the sister plied her needle, when they were interrupted by a knocking at the door. In the atmosphere of vague anxiety and dread that lowered about them in connexion with their fugitive brother, this sound, unusual there, became almost alarming. The brother going to the door, the sister sat and listened timidly. Someone spoke to him, and he replied and seemed surprised; and after a few words, the two approached together.

'Harriet,' said her brother, lighting in their late visitor, and speaking in a low voice, 'Mr Morfin - the gentleman so long in Dombey's House with James.'

His sister started back, as if a ghost had entered. In the doorway stood the unknown friend, with the dark hair sprinkled with grey, the ruddy face, the broad clear brow, and hazel eyes, whose secret she had kept so long!

'John!' she said, half-breathless. 'It is the gentleman I told you of, today!'

'The gentleman, Miss Harriet,' said the visitor, coming in - for he had stopped a moment in the doorway - 'is greatly relieved to hear you say that: he has been devising ways and means, all the way here, of explaining himself, and has been satisfied with none. Mr John, I am not quite a stranger here. You were stricken with astonishment when you saw me at your door just now. I observe you are more astonished at present. Well! That's reasonable enough under existing circumstances. If we were not such creatures of habit as we are, we shouldn't have reason to be astonished half so often.'

By this time, he had greeted Harriet with that able mingling of cordiality and respect which she recollected so well, and had sat down near her, pulled off his gloves, and thrown them into his hat upon the table.

'There's nothing astonishing,' he said, 'in my having conceived a desire to see your sister, Mr John, or in my having gratified it in my own way. As to the regularity of my visits since (which she may have mentioned to you), there is nothing extraordinary in that. They soon grew into a habit; and we are creatures of habit - creatures of habit!'

Putting his hands into his pockets, and leaning back in his chair, he looked at the brother and sister as if it were interesting to him to see them together; and went on to say, with a kind of irritable thoughtfulness:

'It's this same habit that confirms some of us, who are capable of better things, in Lucifer's own pride and stubbornness - that confirms and deepens others of us in villainy - more of us in indifference - that hardens us from day to day, according to the temper of our clay, like images, and leaves us as susceptible as images to new impressions and convictions. You shall judge of its influence on me, John. For more years than I need name, I had my small, and exactly defined share, in the management of Dombey's House, and saw your brother (who has proved himself a scoundrel! Your sister will forgive my being obliged to mention it) extending and extending his influence, until the business and its owner were his football; and saw you toiling at your obscure desk every day; and was quite content to be as little troubled as I might be, out of my own strip of duty, and to let everything about me go on, day by day, unquestioned, like a great machine - that was its habit and mine - and to take it all for granted, and consider it all right.
