How do you mean if he became a suspect? he had to assume he would have been a main suspect as there are only two possible anyway.
He could not have known beforehand that the Police would be convinced it was 4 murders and a suicide?
So many things could have gone wrong on the night that would have given the game away, then there was the advert he placed in the local newspaper!
It was the advert that caught me out, Rob.
I was convinced of Jeremy's innocence: sending him love letters on pink-scented paper, even singing his song in the shower, and then I found out about the advert.
I was crest-fallen, I don't mind telling you. You can well imagine the scene, I'm sure: one day I'm whistling to Justice for Jeremy in my soapsuds, the next I'm all at sea.. But Adam picked me off the floor with his moral support.
