The Special Irish Branch was formed in 1883. It was technically under the command of Detective Chief InspectorAdolphus Williamson, but since he was also responsible for the whole Criminal Investigation Department (CID), Littlechild, as his deputy, was always in effective control. Although he is not thought to have had any direct involvement in the Jack the Ripper investigation,[3] in September 1913 he wrote a letter to journalist G. R. Sims, in which he identified a "Doctor T" (whom he described as "an American quack named Tumblety") as a likely suspect.[4]
Littlechild was promoted to Detective Chief Inspector in 1891. He resigned from the Met in 1893 and worked as a private investigator.[5] He worked for the prosecution in the Oscar Wilde case.[6] In November 1902 he served divorce papers on Arthur Reginald Baker, who days later was murdered by his lover Kitty Byron.[7]
