Sheila (The Glarn Strategy)
From Tardis Wiki, the free Doctor Who reference
Sheila was an estate agent for Morgan Heggarty. She and her co-workers began receiving insulting emails and text messages. They began to turn on each other, but then they received a visit from the Fourth Doctor and Romana I, who informed them that the Glarn intended to invade Earth and were using Morgan Heggarty's employee's as a trial run. The Doctor and Romana, with everyone's help, defeated the Glarn's plan. (PROSE: The Glarn Strategy)
