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. Like Holmes he has gone on to have numerous books and television adaptions but never anywhere near the lofty heights of Holmes's popularity.
