After joining the Indian Civil Service in 1887, Sly was appointed Under-Secretary in the Department of Revenue and Agriculture in 1894. He became officiating Secretary in 1896, before becoming Commissioner of Agriculture and Settlements and later Inspector-General of Agriculture. From 1908–1912 he was Commissioner of Berar Province where he was tasked with remodeling the administration of the province, to bring it in line with the other Central Provinces into which it had recently been amalgamated. In September 1912 he was appointed a member of the Royal Commission on the Public Services. After a brief spell as Commissioner of Nagpur, he was appointed Chairman of the Public Works Department Re-organisation Committee. Sly then went to Bihar and Orissa as Chairman of the Champaran Inquiry Committee. He was later appointed Deputy Chairman of Lord Southborough's Franchise Committee. In January 1920 Sly returned to the Central Provinces as Chief Commissioner, and later that year was appointed Governor of the Central Provinces.
Advocate for reform
Sly played a prominent part in shaping the Government of India Act, as a member of the India Office Committee and a witness before the Joint Parliamentary Committee, where he was a strong advocate of the 1919 changes which became known as the Montagu–Chelmsford Reforms.
Sly married Sophie Louisa Dane on September 4, 1900 at Christ Church, Simla in Bengal. Dane was born in India where her father Sir Richard Morris Dane worked in the Indian Civil Service and was in charge of export. They had one child, Joan Clara Sophia Sly, born in 1902. On 28 July 1910, Sir Frank was granted a divorce from Dane on the grounds of "adultery with Hubert Druce". Sly's daughter Joan joined him in India, where she met her future husband John Ray Geddes.
Joan Sly and John Ray Geddes committed suicide on 8 August 1924 at Gordon Street Chambers on Jermyn Street, London. The inquest into their deaths noted that the couple had taken out extensive loans to fund their wedding and subsequent honeymoon, and had run into financial troubles.
