In the context of Selina Mandrake - The Slayer, Kate (known in the past as Kate Hampshire, Lady Kate Canterson, Mrs. Kate Black, and eventually Prof. Kate Hampshire) is a vampire, who is notable for having slain Lord Buckingham (later known as George), and the more real-life equivalent of Milady de-Winter from Alexandre Dumas’s The Three Musketeers. Nevertheless, Kate looked forward to being superseded by The Dispeller, which was considered the next logical level after slaying, where The Dispeller turned out to be Selina Mandrake, the protagonist of the screenplay.
