Wilkie Collins' 'The Moonstone', published in 1868, is considered to be the first modern mystery employing a crime-detecting hero.

According to an August 1946 Hollywood Reporter news item, Eleanor Parker was given her dual role in this film after she was suspended for refusing to appear in Warner Bros.' Love and Learn (1947).

Filmed in 1946 but not released until 1948.

The music played under the opening titles is the pavane "Earl of Salisbury", written by English renaissance composer William Byrd.

Alexis Smith received top billing in the film's main title credits, while Eleanor Parker received top billing in all of the publicity materials.
