CHAPTER LXXV.
HOW A GENTLEMAN PAID A VISIT AT THE BRASS CASTLE, AND THERE READ A PARAGRAPH IN AN OLD NEWSPAPER.
Dangerfield was, after his wont, seated at his desk, writing letters, after his early breakfast, with his neatly-labelled accounts at his elbow.

There was a pleasant frosty sun glittering through the twigs of the leafless shrubs, and flashing on the ripples and undulations of the Liffey, and the redbreasts and sparrows were picking up the crumbs which the housekeeper had thrown for them outside.

He had just sealed the last of half-a-dozen letters, when the maid opened his parlour-door, and told him that a gentleman was at the hall-step, who wished to see him.
Dangerfield looked up with a quick glance-- 'Eh ?--to be sure.

Show him in.' And in a few seconds more, Mr.Mervyn, his countenance more than usually pale and sad, entered the room.

He bowed low and gravely, as the servant announced him.
Dangerfield rose with a prompt smile, bowing also, and advanced with his hand extended, which, as a matter of form rather than of cordiality, his visitor took, coldly enough, in his.
'Happy to see you here, Mr.Mervyn--pray, take a chair--a charming morning for a turn by the river, Sir.' 'I have taken the liberty of visiting you, Mr.Dangerfield--' 'Your visit, Sir, I esteem an honour,' interposed the lord of the Brass Castle.
A slight and ceremonious bow from Mervyn, who continued--'For the purpose of asking you directly and plainly for some light upon a matter in which it is in the highest degree important I should be informed.' 'You may command me, Mr.Mervyn,' said Dangerfield, crossing his legs, throwing himself back, and adjusting himself to attention.
Mervyn fixed his dark eyes full and sternly upon that white and enigmatical face, with its round glass eyes and silver setting, and those delicate lines of scorn he had never observed before, traced about the mouth and nostril.
'Then, Sir, I venture to ask you for all you can disclose or relate about one Charles Archer.' Dangerfield cocked his head on one side, quizzically, and smiled the faintest imaginable cynical smile.
'I can't _disclose_ anything, for the gentleman never told me his secrets; but all I can relate is heartily at your service.' 'Can you point him out, Sir ?' asked Mervyn, a little less sternly, for he saw no traces of a guilty knowledge in the severe countenance and prompt, unembarrassed manner of the gentleman who leaned back in his chair, with the clear bright light full on him, and his leg crossed so carelessly.
Dangerfield smiled, shook his head gently, and shrugged his shoulders the least thing in the world.
'Don't you know him, Sir ?' demanded Mervyn.
'Why,' said Dangerfield, with his chin a little elevated, and the tips of his fingers all brought together, and his elbows resting easily upon the arms of his chair, and altogether an involuntary air of hauteur, 'Charles Archer, perhaps you're not aware, was not exactly the most reputable acquaintance in the world; and my knowledge of him was very slight indeed--wholly accidental--and of very short duration.' 'May I ask you, if, without leaving this town, you can lay your finger on him, Sir ?' 'Why, not conveniently,' answered Dangerfield, with the same air of cynical amusement.
