Hugo, Earl of Ruven, is sailing home after ten years in India, where he served with his regiment. His grandfather, the old Earl, has died and Hugo has inherited the title and estate of Castle Ruven. He has also inherited his late brother's fiancee, Felice de Lisle. No one who sees the handsome man standing at the rail with his face turned toward the approaching coast suspects the truth. During one of the first battles of the Indian Mutiny, Hugo was severely injured. The new Earl of Ruven is returning home blind.
Meanwhile, Jacina and her father, Doctor Carlton, wait to welcome Hugo to Castle Ruven. Hugo was Jacina's childhood hero and she was devastated to hear of his injury.
From the moment she sees Hugo again her heart is in turmoil. She knows he has a fiancee but considers herself happy just to be in his presence. Although Hugo refuses to be optimistic about the possibility of ever regaining his sight, in Jacina's company his spirits gradually lift.
Then comes the arrival of Felice de Lisle. From this moment on, the lives of Jacina and Hugo are plunged into a world of deception and intrigue. From the misty woods of Ruven to the snowy slopes of Switzerland, their story is played out in an atmosphere of darkness and ever increasing danger.
