Such has been our progress of late years in the art of revealing to the world at large the hidden springs of every action and event around us that a secret is in reality the only thing now impossible. Forty-five years ago, this wonderful exercise of knowledge was in a great measure unknown; the guessers were then a large and respectable class in society, and men were content with what mathematicians call approximation. In our own more accurate days, what between the newspaper, the club-room, and “'Change,” such mystery is no longer practicable. One day, or two at furthest, would now proclaim every item in a man's schedule, and afford that most sympathetic of all bodies, the world, the fruitful theme of expatiating on his folly or his criminality. In the times we refer to, however, it was only the “Con Heffermans” of society that ventured even to speculate on the secret causes of these events. Although the debate had lasted from eight o'clock in the evening to past eleven on the following morning, before twelve Mr. Heffernan's carriage was at the door, and the owner, without any trace of fatigue, set off to ascertain so much as might be learned of this strange and unexpected catastrophe. It was no mere passion to know the current gossip of the day, no prying taste for the last piece of scandal in circulation,--Con Heffernan was above such weaknesses; but he had a habit--one which some men practise even yet with success--of whenever the game was safe, taking credit to himself for casualties in which he had no possible connection, and attributing events in which he had no share to his own direct influence. After all, he was in this only imitating the great navigators of the globe, who have established the rule that discovery gives a right only second to actual creation. This was, however, a really provoking case; no one knew anything of Gleeson's embarrassments. Several of those for whom he acted as agent were in Dublin, but they were more amazed than all others at his flight; most of them had settled accounts with him very lately, some men owed him small sums. “Darcy perhaps knows something about him,” was a speech Heffernan heard more than once repeated; but Darcy's house was shut up, and the servant announced “he had left town that morning.” Hickman O'Reilly was the next chance; not that he had any direct intercourse with Gleeson, but his general acquaintanceship with moneyed men and matters made him a likely source of information; while a small sealed note addressed to Dr. Hickman was in possession of a banker with whom Gleeson had transacted business the day before his departure. But O'Reilly had left town with his son. “The doctor, sir, is here still; he does not go before to-morrow,” said the servant, who, knowing that Heffernan was a person of some consequence in the Dublin world, thought proper to give this piece of unasked news.
