Ms. E is the temporary name of one of the new art style characters. She is a tall, older Caucasian woman with grey hair. She wears a white evening gown with a blue/grey shrug with a flared collar, with a large bow tied on the left just under her bust. She also wears pearl earrings, an elaborate pearl necklace, and a watch.
The internal game files call her "Bea." The SpyParty community has taken to calling her "Helen Mirren" (given her resemblance to the actress) or "Pearl" (for the necklace she wears).
