How much do you know about the couple next door? When Emily and Ben move in next door to Dr Burman and his wife Alisha, they are keen to get to know their new neighbours. Outgoing and sociable, Emily tries to befriend the doctor’s wife, but Alisha is strangely subdued, barely leaving the house, and terrified of answering the phone. When Emily goes missing a few weeks later, Ben is plunged into a panic. His wife has left him a note, but can she really have abandoned him for another man? Or has Emily’s curiosity about the couple next door led her straight into danger? A gripping, sinister thriller with a twist you won’t see coming from the international bestseller Lisa Stone.
