Previously on the storyteller Naked Villainy, Kit Harrison buys the new watch in Edinburgh hours after

Brenda was killed.

He paid for it and filled in the guarantee there and then.

An unexpected visitor turned up at Brenda's flat when she was out of town.

And there was a collar at the door, which surprised me.

On opening the door, it was Kit Harrison.

And Kit's bizarre response when police told him Brenda had died.

It was very unemotional and offhand.

He didn't ask how she died, where she had died. We had died.

It's taken 45 years to bring a killer to court,

and for the first time in UK history,

you'll hear the full murder trial and witness justice being done. It was a

brutal murder of a brilliant woman who was a rising star in genetic research.

It would now be almost like a script from Morse.

The investigator swarming over the dreaming spires of university land.

There was kind of palpable feeling of evil in the air.

I was told it was a massive blood in here.

Two decades on from confronting evil.

So did you kill your ex-wife, Brenda Page?

Evil is being confronted by the law.

Did you kill him?

No.
