A music teacher living alone in a remote village. A strange new pupil who pays in advance for exactly twenty one lessons. The teacher finds himself increasingly preoccupied with the pupil. Uninvited things start changing. The impression of music from the attic. A coded diary slowly relinquishes its treacherous tale. Who is the beautiful and spirited Irish woman whose alluring wit and fondness for quoting Yeat’s poetry intoxicate him? Is she really the visiting freelance writer she claims to be? What is behind her interest in the cottage he rents? Why does she insist there is a cellar there when he has never seen one? What possible reason can there have been for the exorcism once performed in the cottage? When a stranger in the local pub seems to recognize Adrian, the past becomes a predator. As tragedy looms, a voice from the saddest part of him asks ‘how is it that we best deceive ourselves when we are most certain that we do not?
