their loss, your gain
As we know, when famous folk outlive their usefulness they can just disappear into obscurity. So what better way to secure their legacy in the pantheon of celebrity than an untimely death?
Whether via any number of various celebricides or even natural causes, you can turn misfortune and mortality into money. Stick a quid on someone who's maybe been looking a bit peaky, or maybe just got their pilot's licence, and you could be laughing all the way to the bank!
