Rare, however, must have been the mounted traveller in those days, unless visiting Buttermere for itself, for the road led to no further habitations of man, with the exception of some four or five pastoral cabins, equally humble, in Gatesgarth dale. Hither, however, in an evil hour for the peace of this little brotherhood of shepherds, came the cruel spoiler from Keswick, and directed his steps to the once happy cottage of poor Mary, the daughter of Mr. and Mrs. Robinson, an old couple, who kept the inn, and had, by their industry, gained a little property. She was the only daughter, and probably her name had never been known to the public, but for the account given of her by the author of A Fortnight's Ramble to the Lakes in Westmorland, Lancashire, and Cumberland. His errand was to witness or share in char-fishing; for in Derwentwater (the lake of Keswick) no char is found, which breeds only in the deeper waters, such as Windermere, Crummock, Buttermere, &c.

Hatfield now became acquainted with an Irish gentleman, an M.P., who had been resident with his family some months at Keswick. With this gentleman, and under his immediate protection, there was likewise a young lady of family and fortune, and of great personal attractions. One of the means which Hatfield used to introduce himself to this respectable family was the following:—Understanding that the gentleman had been a military man, he took an army list from his pocket, and pointed to his assumed name, the Honourable Alexander Augustus Hope, lieutenant-colonel of the 14th regiment of foot. This new acquaintance daily gained strength; and he shortly paid his addresses to the daughter of the above gentleman, and obtained her consent. The wedding clothes were bought; but previously to the wedding-day being fixed, she insisted that the pretended Colonel Hope should introduce the subject formally to her friends. He now pretended to write letters; and, while waiting for the answers, proposed to employ that time in a trip to Lord Hopetoun's seat, &c.

From this time he played a double game; his visits to Keswick became frequent, and his suit to the young lady assiduous and fervent. Still, however, both at Keswick and Buttermere, he was somewhat shy of appearing in public. He was sure to be engaged in a fishing expedition on the day on which any company was expected at the public house at Buttermere; and he never attended the church at Keswick but once.

Finding his schemes baffled to obtain this young lady and her fortune, he now applied himself wholly to gain possession of Mary Robinson, who was a fine young woman of eighteen, and acted as waiter. In a situation so solitary, the stranger had unlimited facilities for enjoying her company, and recommending himself to her favour. Among the neighbours he made the most minute inquiries into every circumstance relating to her and her family. Doubts about his pretensions never arose in so simple a place as this; they were over-ruled before they could well have arisen, by the opinion now general in Keswick, that he really was what he pretended to be; and thus, with little demur, except in the shape of a few natural words of parting anger from a defeated or rejected rustic admirer, the young woman gave her hand in marriage to the showy and unprincipled stranger. He procured a licence, and they were married in the church of Lorton, on the 2nd of October, 1802. A romantic account of the circumstance found its way almost immediately into the newspapers. It thus fell under the notice of various individuals in Scotland, who knew that Colonel Hope, who was said to have married the flower of Buttermere, had been abroad the whole summer, and was now residing in Vienna. Mr. Charles Hope, then Lord Justice Clerk, afterwards President of the Court of Session (a son-in-law of the Earl of Hopetoun), made the fact known, and prompted inquiries which led to the detection of the imposture.

On the day previous to his marriage, Hatfield wrote to Mr. Mansfield, informing him, that he was under the necessity of being absent for ten days on a journey into Scotland, and sent him a draft for thirty pounds, drawn on Mr. Crumpt, of Liverpool, desired him to cash it, and pay some small debts in Keswick with it, and send him over the balance, as he feared he might be short of cash on the road. This Mr. Mansfield immediately did, and sent him ten guineas in addition to the balance. On the Saturday, Wood, the landlord of the Queen's Head, returned from Lorton with the public intelligence, that Colonel Hope had married the Beauty of Buttermere. As it was clear, whoever he was, that he had acted unworthily and dishonourably, Mr. Mansfield's suspicions were of course awakened. He instantly remitted the draft to Mr. Crumpt, who immediately accepted it. Mr. Mansfield wrote to the Earl of Hopetoun. Before the answer arrived, the pretended honourable returned with his wife to Buttermere. He went only as far as Longtown, when he received two letters, seemed much troubled that some friends whom he had expected had not arrived there, stayed three days, and then told his wife that he would again go back to Buttermere.

From this she was seized with fears and suspicions. They returned, however, and their return was made known at Keswick. The late Mr. Harding, the barrister, and a Welsh judge, passing through Keswick, heard of this impostor, and sent his servant over to Buttermere with a note to the supposed Colonel Hope, who observed, "that it was a mistake, and that it was for a brother of his." However, he sent for four horses, and came over to Keswick; drew another draft on Mr. Crumpt for twenty pounds, which the landlord at the Queen's Head had the courage to cash. Of this sum he immediately sent the ten guineas to Mr. Mansfield, who came and introduced him to the judge, as his old friend Colonel Hope. But he made a blank denial that he had ever assumed the name. He had said his name was Hope, but not that he was the honourable member for Linlithgow, &c., &c.; and one who had been his frequent intimate at Buttermere gave evidence to the same purpose.

In spite, however, of his impudent assertions, and those of his associate, the evidence against him was decisive. A warrant was given by Sir Frederick Vane on the clear proof of his having forged and received several franks as the member for Linlithgow; and he was committed to the care of a constable, but allowed to fish on the lake. Having, however, found means to escape, he took refuge for a few days on board a sloop off Ravenglass, and then went in the coach to Ulverston, and was afterwards seen at a hotel in Chester. In the meantime the following advertisement, setting forth his person and manners, was in the public prints:—

"Notorious Impostor, Swindler, and Felon!

"John Hatfield, who lately married a young woman, commonly called the Beauty of Buttermere, under an assumed name; height about five feet ten inches, aged about forty-four, full face, bright eyes, thick eyebrows, strong, but light beard, good complexion, with some colour, thick, but not very prominent nose, smiling countenance, fine teeth, a scar on one of his cheeks near his chin, very long thick light hair, and a great deal of it gray, done up in a club; stiff, square-shouldered, full breast and chest, rather corpulent, and strong limbed, but very active; and has rather a spring in his gait, with apparently a little hitch in bringing up one leg; the two middle fingers of his left hand are stiff from an old wound; he has something of the Irish brogue in his speech; fluent and elegant in his language, great command of words, frequently puts his hand to his heart; very fond of compliments, and generally addressing himself to persons most distinguished by rank or situation; attentive in the extreme to females, and likely to insinuate himself where there are young ladies. He was in America during the war; is fond of talking of his wounds and exploits there, and of military subjects, as well as of Hatfield Hall, and his estates in Derbyshire and Cheshire; and of the antiquity of his family, whom he pretends to trace to the Plantagenets. He makes a boast of having often been engaged in duels; he has been a great traveller also, by his own account, and talks of Egypt, Turkey, and Italy; and, in short, has a general knowledge of subjects, which, together with his engaging manners, is well calculated to impose on the credulous. He had art enough to connect himself with some very respectable merchants in Devonshire, as a partner in business, but having swindled them out of large sums, he was made a separate bankrupt in June, 1802. He cloaks his deception under the mask of religion, appears fond of religious conversation, and makes a point of attending divine service and popular preachers."

Besides blighting the prospects of the poor girl, he had nearly ruined her father by running up a debt of eighteen pounds. His dressing-case, a very elegant piece of furniture, was left behind, and on being opened at Keswick by warrant of a magistrate, was found to contain every article that the most luxurious gentleman could desire, but no papers tending to discover his real name. Afterwards, Mary herself, searching more narrowly, discovered that the box had a double bottom, and in the intermediate recess, found a number of letters addressed to him by his wife and children, under the name of Hatfield. The story of the detection immediately became as notorious as the marriage had been.
