When Lucas Corinth is invited back to the Alpine town of Gries-am-See, it is as a favoured native son. Since his boyhood there during the War, he has become a world-famous conductor and composer and it is fitting that he be guest of honour at the premiere of his new work, The Horn of Roland.
But over the celebrations falls the shadow of the past; Corinth's presence provokes bitter memories, memories of occupation, danger, secrecy. And from them springs an implacable threat. In revenge for an act of betrayal, Lucas Corinth's life is at risk.
