In 1841, Clare absconded from the asylum in Essex, to walk some 90 miles (140 km) home, believing that he was to meet his first love Mary Joyce; Clare was convinced that he was married to her and Martha as well, with children by both women. He did not believe her family when they told him she had died accidentally three years earlier in a house fire. He remained free, mostly at home in Northborough, for the five months following, but eventually Patty called the doctors in. Between Christmas and New Year in 1841, Clare was committed to the Northampton General Lunatic Asylum (now St Andrew's Hospital). Upon Clare's arrival at the asylum, the accompanying Doctor, Fenwick Skrimshire, who had treated Clare since 1820, completed the admission papers. To the enquiry "Was the insanity preceded by any severe or long-continued mental emotion or exertion?", Dr Skrimshire entered: "After years of poetical prosing." He remained here for the rest of his life under the humane regime of Dr Thomas Octavius Prichard, who encouraged and helped him to write. Here he wrote possibly his most famous poem, I Am.
