Lucas Corinth, now a world-famous conductor and composer, returns with his daughter, Una, to the Alpine town where he grew up in the War. He is to be the guest of honor at a concert and will conduct the world premiere of his new work, "The Horn of Roland."
Out of the memories of his past and the haunting remembrances of occupation, secrecy, and danger springs an implacable threat: Corinth will be killed during his visit in revenge for an act of betrayal many years ago.
Una plays detective in this breathless series of chase and counterchase to the final, unexpected denouement.
