Edgar Drake always believed that he was not made for adventure. One of London's best piano tuners, he leads a measured and calm life in which there is no room for shock. By tuning musical instruments, Edgar fights chaos; for him, harmony and order are the essence of beauty. But one day everything changes. The tuner is asked to go to mysterious Burma, to the most remote outpost of the British Empire, whose eccentric commander ordered himself an exquisite Erard piano. In the humid climate of the wild jungle, the instrument lost its musical perfection. Drake's journey to Asia becomes not only a journey into an unknown and strange world, but also a search for harmony in a world ruled by chaos. It will be a strange adventure in which a humble piano tuner will become the hero of his own life.
