'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.'
