The counsels of the wicked are always dark, and their motives often beyond fathoming; and strange, unaccountable, incredible as it may seem, I do believe, and that upon evidence so clear as to amount almost to demonstration, that Heathcote's visit to Dublin--his betrayal of the secret--and the final and terrible catastrophe which laid O'Mara in the grave, were brought about by no other agent than Dwyer himself. I have myself seen the letter which induced that visit. The handwriting is exactly what I have seen in other alleged specimens of Dwyer's penmanship. It is written with an affectation of honest alarm at O'Mara's conduct, and expresses a conviction that if some of Lady Emily's family be not informed of O'Mara's real situation, nothing could prevent his concluding with her an advantageous alliance, then upon the tapis, and altogether throwing off his allegiance to Ellen--a step which, as the writer candidly asserted, would finally conduce as inevitably to his own disgrace as it immediately would to her ruin and misery. The production was formally signed with Dwyer's name, and the postscript contained a strict injunction of secrecy, asserting that if it were ascertained that such an epistle had been despatched from such a quarter, it would be attended with the total ruin of the writer. It is true that Dwyer, many years after, when this letter came to light, alleged it to be a forgery, an assertion whose truth, even to his dying hour, and long after he had apparently ceased to feel the lash of public scorn, he continued obstinately to maintain. Indeed this matter is full of mystery, for, revenge alone excepted, which I believe, in such minds as Dwyer's, seldom overcomes the sense of interest, the only intelligible motive which could have prompted him to such an act was the hope that since he had, through young O'Mara's interest, procured from the colonel a lease of a small farm upon the terms which he had originally stipulated, he might prosecute his plan touching the property of Martin Heathcote, rendering his daughter's hand free by the removal of young O'Mara. This appears to me too complicated a plan of villany to have entered the mind even of such a man as Dwyer. I must, therefore, suppose his motives to have originated out of circumstances connected with this story which may not have come to my ear, and perhaps never will.
