'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. '.
