Do you think it is possible that Bissey supplied the name of the Escort Service? I know this is way out in left field... but, um.. leave no stone unturned.
I don't know how he would know that to supply it.
He watched them all the time and when he wasn't, his wife did.
They had a running feud going. Bissey admits that. His wife said that they had written the School, the City, the previous owner about having a (defacto) Frat house like that in a residential neighborhood.
You can see how the curtains and yard looked. It looked REAL bad.
