"The holder of a diary is in danger in this deliciously addictive and entertaining psychological thriller set within a Brighton neighbourhood."
Hugely entertaining and addictive, this psychological thriller presses all the klaxon alert buttons from the get-go. The diary of a murdered woman who had been monitoring her neighbours in Brighton holds some very dangerous secrets. Dorothy Koomson is such a consistent writer, her books are oh-so readable, smart and stimulating, and range from family drama and relationship right through to suspense and thrillers. This read is full of suspense and intrigue as it explores family, friendship, and just how well we really know each other. Different characters, all neighbours, head chapters with relevant dates, each person speaking in their own very distinctive voice. These are people who slowly reveal their secrets, and as an added lure the diary secrets are also gradually revealed. I was as hooked as a hooked thing can be as the tension increased, and the explosive ending was just fabulous. This would make a perfect summer read, and though you can just throw yourself in and let go, there are also some thought-provoking themes too. I Know What You’ve Done is a proper page-turner, you may never look at your neighbours in the same way again!
