The Express had the Paul Napier-Fox story as an exclusive. The journalist had gone straight to him and extracted a full admission that Colthorne had dictated the threatening letter. Paul tried to claim he’d gone along with it because Joel had unfairly maligned his integrity, but the journalist had also contacted Barbara Wilson, who did a gleeful job of eviscerating his character and morals. That would teach the swine to bully Aaron as a child.
It shows exactly how much he loves Aaron because he easily could have said "that's what you get for coming after me."
