What happened in Professor T season 3 finale?

The finale left us with two huge revelations that have left fans reeling. Firstly, we discover that The Professor’s (Ben Miller) father didn’t die of suicide, but had actually been killed by his mother during one of his drunken outbursts. Speaking in an interview with the Radio Times about the revelation, Miller said: “It's huge. It's seismic because he realises that his mother made a huge sacrifice for him and that he's completely got her wrong, really.”

The finale also saw series favourite DS Lisa Donckers (Emma Naomi) die after being knocked down by a car whilst out on duty, after being proposed to by her partner DS Dan Winters.
