Michael Glenn's roles included Daisy the scullery maid, Scotland Yard Inspector Lestrade and Sir Henry Baskerville.^[1] Author Ludwig wanted to infuse suspense with humor saying "You’re not making fun of the genre, [but] at the same time, there’s a lot of laughs, because they come out of the tension."^[1]

Although the opening stage direction to Act One sets the action in the late 1890s, Act 1 Scene 3 has the two main protagonists attending a performance of Puccini's opera Tosca, at Covent Garden. This opera was first performed in Rome on January 14, 1900, and did not receive its London première until July 12, 1900.^[9]
