Anderson began to practice as a
barrister. However, in 1865, his father showed him papers relating to the trials of
Fenians and he too became involved in the operations against them, becoming the foremost expert on the Fenians and operations against them. In 1868, he was called to London, following the murder of a policeman in
Manchester during a Fenian jailbreak in September 1867 (see
Manchester Martyrs) and the bombing of
Clerkenwell Gaol in another rescue attempt three months later (see
Clerkenwell Outrage). In April 1868, he was attached to the
Home Office as adviser on political crime. However, although Anderson remained in this post, Fenianism became more or less dormant, and to justify his salary he was appointed secretary to several government inquiries. In 1877, he was appointed secretary to the new
Prison Commission. In the early 1880s, however, the Fenians began operations again and in 1883, they commenced a bombing campaign in England. Anderson was not particularly effective in combating them, and in May 1884 he was forced to resign his Home Office post, to be replaced by
Edward Jenkinson. In 1886, he was also removed from the Prison Commission. In 1887, Jenkinson resigned, and Anderson was once again the only man available with experience in anti-Fenian activities. He was asked to assist
James Monro, Assistant Commissioner (Crime) at
Scotland Yard, in operations related to political crime. In 1888, Monro resigned (although he became
Commissioner later that year), and Anderson replaced him as Assistant Commissioner, the post he was to hold for the rest of his career. Anderson retired in 1901, and was appointed
Knight Commander of the Order of the Bath (KCB) in the King's
Birthday Honours List in November 1901, having been appointed
Companion of the Order of the Bath (CB) in 1896.
Jack the Ripper investigation The
Criminal Investigation Department (CID) was then just starting the investigation into the
Jack the Ripper murders, which he thought were grossly over-sensationalized. Almost immediately after being promoted, Anderson went on vacation in Switzerland on doctor's orders, leaving the
Metropolitan Police leaderless during the biggest challenge in its history. He was called back after a month because of increased bad publicity over the Ripper murders. About which, he later wrote, "When the stolid English go in for a scare, they take leave of all moderation and common sense. If nonsense were solid, the nonsense that was talked and written about those murders would sink a
Dreadnought.” He also wrote that the victims "belonged to a very small class of degraded women who frequent the East End streets after midnight, in hope of inveigling belated drunkards, or men as degraded as themselves". He did not lead the Metropolitan Police to capture the killer. ==Religion==
