Is anyone watching?

I do worry about my internet browsing. While researching for my stories I end up accessing all sorts of strange sites and if the American listening station at Menwith Hill - which is really not that far from where I live- has a bank of machines looking out for key words - I might be in for a visit from the police at some point.
EG - I wanted to know what the insides of the MI5 and MI6 and New Scotland Yard buildings were like - what security there was etc
        I wanted to know what could be used to disguise the odour of cocaine to fool a sniffer dog
        I wanted to know how much of a dead baby would be left after being left in a dry cold environment for several years
      And a lot of other searches for sex related stuff. The latest yesterday involved me checking out a male escort site. To my astonishment I spotted a picture of my husband. Well, it wasn't, but it really looked like him. The guy was available for fifty pounds an hour and no sex. Hmm - wonder if he' do the dishes, the garden, the windows, the shopping.....
