The first appearance of Maria Bello, who guest stars and eventually becomes a full cast member.
One of the twins says "I've read enough Agatha Christie to know that the simplest explanation is never the right one.". This is true for Agatha Christie's novels. The latter half of the line, though, is a play on Occam's Razor which states that the simplest explanation is usually the right one.
Maria Bello appears as Agent Sloane. In 1999 she appeared in Payback (1999) along with Jack Conley whose character (Sportelli) was killed in the previous episode. His character both times was that of a corrupt police officer.
Another Star Trek alumni guest star in this episode. This time is Gates McFadden as the victims mother.
