Alone again, Clennam became a prey to his old doubts in reference to his mother and Little Dorrit, and revolved the old thoughts and suspicions. They were all in his mind, blending themselves with the duties he was mechanically discharging, when a shadow on his papers caused him to look up for the cause. The cause was Mr Pancks. With his hat thrown back upon his ears as if his wiry prongs of hair had darted up like springs and cast it off, with his jet-black beads of eyes inquisitively sharp, with the fingers of his right hand in his mouth that he might bite the nails, and with the fingers of his left hand in reserve in his pocket for another course, Mr Pancks cast his shadow through the glass upon the books and papers.

Mr Pancks asked, with a little inquiring twist of his head, if he might come in again? Clennam replied with a nod of his head in the affirmative. Mr Pancks worked his way in, came alongside the desk, made himself fast by leaning his arms upon it, and started conversation with a puff and a snort.

'Mr F.'s Aunt is appeased, I hope?' said Clennam.

'All right, sir,' said Pancks.

'I am so unfortunate as to have awakened a strong animosity in the breast of that lady,' said Clennam. 'Do you know why?'

'Does _she_ know why?' said Pancks.

'I suppose not.'

'_I_ suppose not,' said Pancks.

He took out his note-book, opened it, shut it, dropped it into his hat, which was beside him on the desk, and looked in at it as it lay at the bottom of the hat: all with a great appearance of consideration.

'Mr Clennam,' he then began, 'I am in want of information, sir.'

'Connected with this firm?' asked Clennam.

'No,' said Pancks.

'With what then, Mr Pancks? That is to say, assuming that you want it of me.'

'Yes, sir; yes, I want it of you,' said Pancks, 'if I can persuade you to furnish it. A, B, C, D. DA, DE, DI, DO. Dictionary order. Dorrit. That's the name, sir?'

Mr Pancks blew off his peculiar noise again, and fell to at his right-hand nails. Arthur looked searchingly at him; he returned the look.

'I don't understand you, Mr Pancks.'

'That's the name that I want to know about.'

'And what do you want to know?'

'Whatever you can and will tell me.' This comprehensive summary of his desires was not discharged without some heavy labouring on the part of Mr Pancks's machinery.

'This is a singular visit, Mr Pancks. It strikes me as rather extraordinary that you should come, with such an object, to me.'

'It may be all extraordinary together,' returned Pancks. 'It may be out of the ordinary course, and yet be business. In short, it is business. I am a man of business. What business have I in this present world, except to stick to business? No business.'

With his former doubt whether this dry hard personage were quite in earnest, Clennam again turned his eyes attentively upon his face. It was as scrubby and dingy as ever, and as eager and quick as ever, and he could see nothing lurking in it that was at all expressive of a latent mockery that had seemed to strike upon his ear in the voice.
