The Forty Thieves is a "Pantomime Burlesque" written by Robert Reece, W. S. Gilbert, F. C. Burnand and Henry J. Byron, created in 1878 as a charity benefit, produced by the Beefsteak Club of London.
This entertainment was first produced at the Gaiety Theatre by its proprietor, John Hollingshead (also a member of the Club), as the Wednesday matinee on 13 February 1878.
[2] Robert Soutar (Nellie Farren's husband) acted as director/stage manager, with John D'Auban choreographing the Harlequinade that was played at the end of the pantomime.
"[5] Proceeds from the first performance of the piece were 700 pounds sterling, owing to a sell-out charity crowd paying enhanced prices.
The entertainment was presented again, with similar success, at Brighton on 9 March 1878 and again at the Gaiety on 10 April, to benefit wives and children of seamen killed in the sinking of HMS Eurydice.
