The Locket

Norma Barzman's lengthy treatment for this film, which Sheridan Gibney revised into a screenplay, was inspired by a true event which was recounted to her by financier George Peabody Gardner and his sister Belle. When younger, the Gardners eschewed their aristocratic upbringing partly in reaction to an incident in their youth: As children they became friendly with the daughter of the family's housekeeper. It transpired that the daughter was wrongly accused of stealing a locket, leading to the firing and departure of the housekeeper and her daughter. Years later, they learned that the daughter suffered from depression and was implicated in a theft, a consequence for which the Gardners felt their family was partly responsible.

American ambulances, shown driven with left-hand drive, were not used in wartime London.
