Who was Gabriel Ferranti? Why had he disappeared?

Jocelyn Irvin has just returned from the Boer War with an incurably lamed leg. He heads for the cathedral town or Torminster, where he recovers his love of life in the invigorating company of his cousin, Hugh Anthony, his grandfather, the Canon and Henrietta.

When Jocelyn moved into the little house where Ferranti once had lived, a dark Byronic spirit haunted its rooms. Was Ferranti alive or dead? Until they knew, Jocelyn and Felicity must reach out to him. Until Ferranti no longer needed them, they must yield slowly to the madness of love. So the ghost of Gabriel Ferranti guided their lives in surprising ways, and more than one bewildered heart was restored to the wonder and magic of living.
