They found Jason at the bottom of the cliff. His body lay there quietly, mangled and bloody, his clothes torn as he'd fallen right into a patch of stony bramble bushes.

Linda screamed, really loud. I felt a bit sorry for her, and for a moment I wanted to go back, to change things, but it was too late. What was done was done.

Jason had killed himself, the medics said when they arrived. He'd jumped. That's what it looked like, anyway. He'd simply stepped off the cliff. Why, no one understood. He'd been happy, he had a beautiful girlfriend and a pleasant family, he did reasonably well in school and had about five loyal friends.

There was never a question of who: Linda knew so little. It was only a question of how.
