Ainsworth's father died on 20 June 1824 and Ainsworth became a senior in the law firm and began to focus on his legal studies. To this end he left for London at the end of 1824 to study under Jacob Phillips, a barrister at King's Bench Walk. Ainsworth lived at Devereux Court, a place that was favoured by Augustan writers. During his stay, he visited Lamb, but felt let down by the real Lamb. Ainsworth attended Lamb's circle, and met many individuals including Henry Crabb Robinson and Mary Shelley. During the summer of 1825, Ainsworth returned on a trip to Manchester in order to meet Crossley before travelling to the Isle of Man. He continued to write, and a collection of his poems called "The Works of Cheviot Tichburn, with the types of John Leigh" was published. He also had two works published in "The Literary Souvenir", a magazine published by John Ebers.
