When you think about it, almost everyone lies on the show!!!
Yes, Vicky was the exception and she sure got herself into a lot of trouble for her honesty, and it didn't help when Peter Bradford decided to be honest in the trial.
Professor Stokes is a pretty honest guy, though he just doesn't blurt out everything that comes to his mind. I always got the impression he knew more about the things going on around him than he let on, but that doesn't make him a liar.
I guess it wouldn't make for good drama if everyone told the truth on this and other shows (especially soaps).
If they would just tell the truth from the beginning, it would save everyone some grief.
