Doctor Who Warlock by Andrew Cartmel

This single source provides excerpts from a novel, likely a Doctor Who adventure titled Warlock, focusing on the companions Ace and Benny, as well as an undercover detective named Creed McIlveen. The narrative follows Ace’s daily life at the Doctor's house, including a missing kettle and an encounter with her cat, Chick, who is later kidnapped. Simultaneously, a parallel storyline involves Creed’s investigation into a powerful, mind-altering drug called "warlock" and a confrontation with drug dealers, the Mayans, which ends violently and links back to the mysterious International Drug Enforcement Agency (IDEA). The overall plot centers on the drug's nature as a sentient entity capable of inhabiting and transferring human consciousness, culminating in the villainous IDEA director, Harrigan, attempting to use the drug to possess a man named Vincent.
