Nine Lives

If you're on the list you're marked for death. The envelope is unremarkable. There is no return address. It contains a single, folded, sheet of white paper.

The envelope drops through the mail slot like any other piece of post. But for the nine complete strangers who receive it - each of them recognising just one name, their own, on the enclosed list - it will be the most life altering letter they ever receive.

It could also be the last, as one by one, they start to meet their end. But why?
