These days it often seems that nothing is as it seems.
Remember when match-fixing in cricket still shocked us or when Tiger Woods was a clean-living young golfer?
What next? Maybe a trusted figure from our youth would be exposed for his double life.
Well, that is exactly what happened last week. Australian children's entertainer Rolf Harris was convicted for abuse. The ultimate betrayal?
As someone who grew up watching Harris bring the most marvellous drawings to life on television, it was quite a shock when he was first arrested for indecently assaulting four girls for almost two decades.
