'Deliciously ingenious.' Daily Mail 'Keeps you guessing right to the end.' PETER MAY 'Smartly entertaining.' Washington Post 'So beautifully written, so gripping, so perfect.' SOPHIE HANNAH 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.'
