I want to know the answer to the following question:
Which Bond novel first featured Spectre?
All the background I'm provided with is that "The ownership of the Spectre organisation—originally stylised "SPECTRE" as an acronym of SPecial Executive for Counter-intelligence, Terrorism, Revenge and Extortion—and its characters, had been at the centre of long-standing litigation starting in 1961 between Ian Fleming and Kevin McClory over the film rights to the novel Thunderball.". Is that enough to answer the question?
Answer: yes
