Gabriel cheerfully complied, and the coachman mounting his box drove off.

'Varden,' said Mr Haredale, after a minute's pause, 'you will be amazed to hear what errand I am on; it will seem a very strange one.'

'I have no doubt it's a reasonable one, sir, and has a meaning in it,' replied the locksmith; 'or it would not be yours at all. Have you just come back to town, sir?'

'But half an hour ago.'

'Bringing no news of Barnaby, or his mother?' said the locksmith dubiously. 'Ah! you needn't shake your head, sir. It was a wild- goose chase. I feared that, from the first. You exhausted all reasonable means of discovery when they went away. To begin again after so long a time has passed is hopeless, sir--quite hopeless.'

'Why, where are they?' he returned impatiently. 'Where can they be? Above ground?'

'God knows,' rejoined the locksmith, 'many that I knew above it five years ago, have their beds under the grass now. And the world is a wide place. It's a hopeless attempt, sir, believe me. We must leave the discovery of this mystery, like all others, to time, and accident, and Heaven's pleasure.'

'Varden, my good fellow,' said Mr Haredale, 'I have a deeper meaning in my present anxiety to find them out, than you can fathom. It is not a mere whim; it is not the casual revival of my old wishes and desires; but an earnest, solemn purpose. My thoughts and dreams all tend to it, and fix it in my mind. I have no rest by day or night; I have no peace or quiet; I am haunted.'

His voice was so altered from its usual tones, and his manner bespoke so much emotion, that Gabriel, in his wonder, could only sit and look towards him in the darkness, and fancy the expression of his face.

'Do not ask me,' continued Mr Haredale, 'to explain myself. If I were to do so, you would think me the victim of some hideous fancy. It is enough that this is so, and that I cannot--no, I can not--lie quietly in my bed, without doing what will seem to you incomprehensible.'

'Since when, sir,' said the locksmith after a pause, 'has this uneasy feeling been upon you?'

Mr Haredale hesitated for some moments, and then replied: 'Since the night of the storm. In short, since the last nineteenth of March.'

As though he feared that Varden might express surprise, or reason with him, he hastily went on:

'You will think, I know, I labour under some delusion. Perhaps I do. But it is not a morbid one; it is a wholesome action of the mind, reasoning on actual occurrences. You know the furniture remains in Mrs Rudge's house, and that it has been shut up, by my orders, since she went away, save once a-week or so, when an old neighbour visits it to scare away the rats. I am on my way there now.'

'For what purpose?' asked the locksmith.

'To pass the night there,' he replied; 'and not to-night alone, but many nights. This is a secret which I trust to you in case of any unexpected emergency. You will not come, unless in case of strong necessity, to me; from dusk to broad day I shall be there. Emma, your daughter, and the rest, suppose me out of London, as I have been until within this hour. Do not undeceive them. This is the errand I am bound upon. I know I may confide it to you, and I rely upon your questioning me no more at this time.'

With that, as if to change the theme, he led the astounded locksmith back to the night of the Maypole highwayman, to the robbery of Edward Chester, to the reappearance of the man at Mrs Rudge's house, and to all the strange circumstances which afterwards occurred. He even asked him carelessly about the man's height, his face, his figure, whether he was like any one he had ever seen--like Hugh, for instance, or any man he had known at any time--and put many questions of that sort, which the locksmith, considering them as mere devices to engage his attention and prevent his expressing the astonishment he felt, answered pretty much at random.

At length, they arrived at the corner of the street in which the house stood, where Mr Haredale, alighting, dismissed the coach. 'If you desire to see me safely lodged,' he said, turning to the locksmith with a gloomy smile, 'you can.'

Gabriel, to whom all former marvels had been nothing in comparison with this, followed him along the narrow pavement in silence.
