"Here is a written description of the persons of this gang of blacklegs, swindlers, and forgers," concluded the commissioner, summing up his instructions. "It will be your object to discover their private haunts, and secure legal evidence of their nefarious practices. We have been hitherto baffled, principally, I think, through the too hasty zeal of the officers employed: you must especially avoid that error. They are practised scoundrels; and it will require considerable patience, as well as acumen, to unkennel and bring them to justice. One of their more recent victims is young Mr. Merton, son, by a former marriage, of the Dowager Lady Everton.

"This note informs me that you have been selected for the duty of endeavoring to extricate my son from the perilous entanglements in which he has unhappily involved himself." I was about to reply--for I was silly enough to feel somewhat nettled at the noble lady's haughtiness of manner--that I was engaged in the public service of extirpating a gang of swindlers with whom her son had involved himself, and was there to procure from her ladyship any information she might be possessed of likely to forward so desirable a result; but fortunately the remembrance of my actual position, spite of my gentleman's attire, flashed vividly upon my mind;
