One unexpected call. One terrifying truth. The Good Listeners are there for anyone who needs to talk. When the phone rings, a Good Listener has no idea who could be at the other end.The woman cheating on her husband, the man who has lost yet another job, the teenager struggling at school... And Clara is prepared for every kind of caller. Except this one. Because the woman on the other end of the line has just told her ‘my husband killed a little girl.’And two years ago, Clara’s own daughter was murdered and her killer never caught. The police have no leads. This is Clara's only chance of justice. But when the caller is anonymous, what chance does she have of finding them?
