Good question - Sally and her boss, forgot his name, she was his PA at the car show room. This has always annoyed me, either I missed an episode when she got caught or she didn't get caught. I think his wife, suspected him, but THEY weren't caught asuch, if that makes sense.
Arse. It sounds like a Soap-y thing to do though. I will think hard as I have always pondered this too. The discovery is usually whilst the illicit couple are mid snog and ends with one or both of them wearing a drink too.
Its a bit hard to answer though isn't it, as soaps never blinking end, mores the pity! Did Max ever erase that video camera footage of him and Stacey getting up close?? Ooh what a cliffhanger, not.
Perhaps there was some triangle of love in Crossroads, Howards Way, Brookside or Eldroado that never got revealed "in the end"!
the laws on criminals getting away with sytuff in films changed in the 70's, cos that Ryan O'neal film was the first film released after the law changed, I think it was called The Driver but not sure.
