The Lady in the Iron Mask

The plot-line shown in the beginning (a woman with a veil enters and tells how a jealous lover threw acid in her face - destroying both her face and voice) is based on the (very true) story of Linda Pugach, and Burt Pugach, whose story was told in the documentary, Crazy Love (2007) (BTW similar to what the veiled woman says in the beginning - about wanting David and Maddie to find the man - not for revenge, but for possible love, the real Pugachs - as their surname indicates - did subsequently get married after Burt had served time for the act. Though not exactly a 'fairytale romance' - at least to Linda Pugach - Burt was always very much in love with Linda, to her last breath. Though she never outright said otherwise, it was clear that Linda was fearful no one else would want her after the incident, and Burt - a lawyer by profession - always treated her as a princess).

In the chase scene near the end of the episode. It's clearly shown that a maintenance worker is shampooing a carpeted floor in the Hotel lobby, but the worker is using a floor buffer and not a carpet cleaner, it's shown that he's producing a ton of soapy bubbles that the characters slip and fall upon. Carpets when cleaning wouldn't produce a ton of soap nor would they be that wet to cause people to slip and fall, then go sliding.

When originally aired, the chase at the end of this episode was scored to the "William Tell Overture." When released on DVD, that music had been replaced by more sedate studio orchestration.
