Until recently, the most exciting thing that that happened in Ashdown Close was a parcel going missing. That was before the arrival of Sian and Richard at number 8. They are cool, glamorous, and everything that Kitty hoped her life in London would be. Kitty can’t help but be dazzled by her new neighbours, and makes it her mission to befriend them. But when she sees a mysterious stranger leaving their house, she realises they might not be the perfect couple she thought. Aided and abetted by her reluctant best friend Grace, Kitty is determined to find out the truth. But nosy neighbouring has consequences. And on a street where everyone knows everything, what if you uncover more than you bargained for?
