Mr. E

""I hate them because they gave birth to you!""

- Ms. E to Benjamin Ripley in Spy School British Invasion

Mr. E is the mysterious leader of SPYDER who has eluded the CIA's grasp until Spy School British Invasion, when Ben confronts her for the first time. It is revealed that Mr. E is actually a woman, and will be referred to as "Ms. E" from then on. Her real name still remains unknown. She is captured at the end of Spy School British Invasion.

Backstory
Ms. E was a CIA agent who graduated from the same class as Alexander Hale. She claims she was a much better agent than Alexander, which was probably true considering Alexander's skill level (refer to the books), but Alexander rose to the top, while Ms. E was given much less important jobs. She despises the sexism present in the espionage industry. This is the main reason why Ms. E started the evil organization SPYDER, where she is highly respected as the leader as wells as followed.

Appearance & Personality
When Ben and the spies first encounter Ms. E in her hideout in France, she is dressed as a maid and looks like a frail, old lady. She is actually about as old as Alexander Hale. Ms. E is naturally devious and scheming, almost to the point of instability, as she's become bent on pulling off her evil plans and preventing Ben from foiling them again.

Skills & Abilities
Despite her old maid cover, Ms. E proved to still be very strong and dangerous. She used to be a comptetent analyst at the CIA, and now is the leader of an evil organization, being very secretive and deceptive and having orchestrated many of SPYDER's evil schemes. She can speak French.
