This time around it is The Poluski Brothers William Nelson Govett & his brother, Samuel Thomas Govett - a popular music hall comedy double act from the 1880s up until the First World War.
Their claim to Holmes fame comes from their performance in "The Sleeping Beauty" a pantomime for children. The Poluski Brothers appeared as Detectives Holmes & Blake (a parody of Sherlock Holmes & Sexton Blake) who search for Auriol, who has been transformed by Anarchista into an ugly beast.
For those unaware, Sexton Blake is a 19th Century fictional detective who had his basis in Sherlock Holmes.
