A novel written in three volumes. In the golden age of steam, the London train wends its way across the Tamar into the strange and mystic land that is Cornwall, having left most of its length at Plymouth. A weary doctor gazes at the countryside, when the train grinds to a halt and his professional attention is demanded. A young woman. An apparent suicide. Who was she? What brought her to Cornwall? What drove her to kill herself? Or did she? - Summary by Lynne Thompson
