'Deliciously ingenious' Daily Mail
'Smartly entertaining' Washington Post

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?

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.'
