Letters of Stanley Kubrick

Anyone who knows me knows I am a huge fan of Stanley Kubrick's films. So it's probably no surprise that I tend to eat up anything related to him. I was interested and happy to find some letter's from him that the Telegraph in the U.K. had posted. What I found most fascinating, though, was this letter from his personal assistant: 

February 25, 1982 
From Tony Frewin
Lee Tracy and co can do de-bugging sweeps of the house and premises and the price depends on the size. Lee can do a full bugging sweep of a room testing to see that the mains aren't used for transmissions and also check a phone line for bugs etc for about £75 to £100.

Good heavens! Why in the world did Kubrick think he had to worry about bugs somewhere? Tell me more, tell me more!
