Agggh doing my head in!!!
Set in current time but the crime happened a few years ago.
Bloke happily married and an old Fagan looking character turns up at his house.
Turns out a woman had been killed after a night out and they buried her body.
There was news that developers were going to build on the area where her body was. The younger guy is convinced he had killed her but the twist was something like the older had actually had a twisted fantasy and planned everything.
It's bugging me trying to think what was!
