In 1784, his Grace of Rutland was appointed Lord Lieutenant of Ireland; and shortly after his arrival in Dublin, Hatfield made his appearance in that city. He immediately, on his landing, engaged a suite of rooms at a hotel in College Green, and represented himself as nearly allied to the Viceroy, but that he could not appear at the castle until his horses, servants, and carriages were arrived, which he ordered, before leaving England, to be shipped at Liverpool. The easy and familiar manner in which he addressed the master of the hotel, perfectly satisfied him that he had a man of consequence in his house, and matters were arranged accordingly. This being adjusted, Hatfield soon found his way to Lucas's coffee-house, a place which people of a certain rank generally frequent; and, it being a new scene, the Yorkshire park, the Rutlandshire estate, and the connection with the Rutland family, stood their ground very well for about a month.

At the expiration of this time, the bill at the hotel amounted to £60 and upwards. The landlord became importunate, and after expressing his astonishment at the non-arrival of Mr. Hatfield's domestics, etc., requested he might be permitted to send in his bill. This did not in the least confuse Hatfield; he immediately told the master of the hotel, that very unfortunately his agent, who received the rents of his estates in the north of England, was then in Ireland, and held a public employment; he lamented that his agent was not then in Dublin, but he had the pleasure to know his stay in the country would not exceed three days. This satisfied the landlord; and at the expiration of the three days, he called upon the gentleman whose name Hatfield had given him, and presented the account. Here followed another scene of confusion and surprise. The supposed agent of the Yorkshire estate very frankly told the man who delivered the bill, that he had no other knowledge of the person who sent him than what common report furnished him with, that his general character in London was that of a romantic simpleton whose plausibilities had imposed on several people, and plunged himself into repeated difficulties.

The landlord retired, highly thankful for the information, and immediately arrested his guest who was lodged in the prison of the Marshalsea. Hatfield had scarcely seated himself in his new lodgings, when he visited the jailor's wife in her apartment, and in a whisper, requested of her not to tell any person that she had in her custody a near relation of the then Viceroy. The woman, astonished at the discovery, immediately showed him into the best apartment in the prison, had a table provided, and she, her husband, and Hatfield, constantly dined together, for nearly three weeks, in the utmost harmony and good humour.

During this time he had petitioned the Duke for another supply, who, apprehensive that the fellow might continue his impositions in Dublin, released him, on condition of his immediately quitting Ireland; and his grace sent a servant, who conducted him on board the packet that sailed the next tide for Holyhead.

In 1792, he came to Scarbro', introduced himself to the acquaintance of several persons of distinction in that neighbourhood, and insinuated that he was, by the interest of the Duke of Rutland, soon to be one of the representatives in parliament for the town of Scarbro'. After several weeks' stay at the principal inn, his imposture was detected by his inability to pay the bill. Soon after his arrival in London, he was arrested for this debt, and thrown into prison. He had been eight years and a half in confinement, when a Miss Nation, of Devonshire, to whom he had become known, paid his debts, took him from prison, and gave him her hand in marriage.

Soon after he was liberated, he had the good fortune to prevail with some highly respectable merchants in Devonshire to take him into partnership with them; and, with a clergyman to accept his drafts to a large amount. He made upon this foundation a splendid appearance in London; and, before the general election, even proceeded to canvass the rotten burgh of Queenborough. Suspicions in the meantime arose, in regard to his character, and the state of his fortune. He retired from the indignation of his creditors, and was declared a bankrupt, in order to bring his villanies to light. Thus, having left behind his second wife and two infant children at Tiverton, he visited other places; and, at length, in July, 1802, arrived at the Queen's Head in Keswick, in a handsome travelling carriage, but without any servant, where he assumed the name of the Hon. Alexander Augustus Hope, brother of the Earl of Hopetoun, M.P., for Linlithgow.

From Keswick, as his head-quarters, he made excursions in every direction amongst the neighbouring valleys; meeting, generally, a good deal of respect and attention, partly on account of his handsome equipage, and still more from his visiting cards, which designated him as "the Honourable Alexander Augustus Hope." Some persons had discernment enough to doubt of this; for his breeding and deportment, though showy, had a tinge of vulgarity about it; he was grossly ungrammatical in his ordinary conversation. He received letters under this assumed name—which might be through collusion with accomplices—but he himself continually franked letters by that name. That being a capital offence, not only a forgery, but (as a forgery on the post-office) sure to be prosecuted, nobody presumed to question his pretensions any longer; and henceforward, he went to all places with the consideration attached to an earl's brother. All doors flew open at his approach; boats, boatmen, nets, and the most unlimited sporting privileges, were placed at the disposal of the "Honourable" gentleman; and the hospitality of the whole country taxed itself to offer a suitable reception to the patrician Scotchman.

Nine miles from Keswick, by the nearest route, lies the lake of Buttermere. Its margin, which is overhung by some of the loftiest and steepest of Cumbrian mountains, exhibits on either side few traces of human neighbourhood; the level area, where the hills recede enough to allow of any, is of a wild, pastoral character, or almost savage; the waters of the lake are deep and sullen; and the barrier mountains, by excluding the sun for much of its daily course, strengthen the gloomy impressions. At the foot of this lake (that is, at the end where its waters issue), lie a few unornamented fields, through which rolls a little brook-like river, connecting it with the larger lake of Crummock; and at the edge of this little domain, upon the roadside, stands a cluster of cottages, so small and few, that, in the richer tracts of the islands, they would scarcely be complimented with the name of hamlet. One of these, the principal, belonged to an independent proprietor, called, in the local dialect, a "Statesman;" and more, perhaps, for the sake of gathering any little local news, than with much view to pecuniary profit at that era, this cottage offered the accommodations of an inn to traveller and his horse.
