WILLIE McClean was one of the more colourful characters to give evidence against Nevin. He admitted to an 18-month sexual affair with her.
On August 3, 1996, McClean was interviewed by Sergeants Joe O'Hara and Brian Duffy. Far from being shocked, he showed absolutely no surprise, and gave the impression that he was expecting such a visit. Friendly to a fault, he invited his two guests into the house.
What contacts had he previously had with Catherine, and why did she have the number of his girlfriend's car on a piece of paper? All was to be revealed.
