In 1806, he finally disposed of his Staffordshire properties, pulling down the derelict Elmhurst Hall. He moved back to London full-time, and took an oath as a Commissioner of Public Accounts, based at Somerset House in the Strand. Around this time he became a man of letters, addressing the foremost politicians of the time, while also writing for a magazine — The Aegis. The next year, he attempted to be elected as MP for Westminster in the 1807 United Kingdom general election. On Friday 8 May 1807, he attended a meeting at Covent Garden, London where he was introduced to the meeting, by Col. Robinson who at that time commanded London Recruiting District, and the Pimlico battalion of the Queen's Loyal Volunteers from about 1803. His election was unsuccessful and he returned to his literary pursuits.
