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.

What readers are saying:

***** 'It gripped me from start to finish.'

***** 'Prepare to be blown away.'

***** 'Another fast paced edge of your seat masterclass.'

***** 'What an absolutely wild ride.'

***** 'Best Peter Swanson murder mystery I've read.'

***** 'An absolute winner . . . A must read for lovers of a good thriller.'
