the newspaper into the best evening journal of the period, thanks in part to his securing contributors including Rudyard Kipling and H. G. Wells. Yet Cust rejected contributions submitted by Astor himself, who had literary aspirations; and this, coupled with political disagreements, led to Cust's dismissal in February 1896. After leaving the Pall Mall Gazette, Cust continued his career as an author. He wrote several poems, most notably "Non nobis". During World War I Cust was active in propaganda on behalf of the British Government. In August 1914 he founded the Central Committee for National Patriotic Organizations. Death He died in 1917 of a heart attack at his home in Hyde Park Gate, London. As the most senior male relative of his childless second cousin Adelbert Brownlow-Cust, 3rd Earl Brownlow, 3rd Viscount Alford, 4th Baron Brownlow, 7th Baronet (1844–1921), he had been the heir apparent to the barony of Brownlow, the Cust baronetcy and to the extensive Cust estates centred on Belton House.

Illegitimate descendants Lady Diana Cooper His best-known lovechild was the socialite Lady Diana Cooper (1892-1986), legally the daughter of Henry Manners, 8th Duke of Rutland. Internationally famous for her beauty, she married the politician Duff Cooper in 1919. Lady Thatcher (rumoured) A long-standing rumour has held that Cust had an affair with a servant at Belton House called Phoebe Stephenson, who consequently gave birth to a daughter named Beatrice, who having married Alfred Roberts, a grocer in nearby Grantham, became the mother of Margaret Thatcher, Prime Minister of the United Kingdom. In the 1980s, the very elderly Diana Cooper referred to Thatcher as "my niece, the Prime
