Felicity Gregson was a young woman who contacted Madame Vastra several days before her death about a light with trailing smoke and fire that fell from the sky behind her house. She claimed that the crash site had been cleaned overnight, but she still had physical evidence to show Vastra in person. They were supposed to meet at the Ranskill Gardens, but due to Madame Vastra's double booking at the Greek Embassy, she sent her butler, Strax, instead. Before Strax had been able to meet with her, she was shot through the heart while hiding behind a snowman built by Harry and Jim. The force of the bullet shoved her body into the back of the snowman and after her body crushed the remainder of the melting snowman, she died. (PROSE: Devil in the Smoke)
