It doesn't get much better than this. Missing British canoeist turns himself into police claiming no memory of the past five years. Wife has since moved to Panama and claimed the life insurance money. She's now failed to rock up to Heathrow (her plane had a brief stopover in Madrid...). Now one of the sons is missing and he's left behind a coded notebook for the girlfriend.
Yet if we wrote a story like this in a novel, people would throw the book against the wall and say "as if!" hahahahah.
