It's Christmas Eve in London's financial district. A billionaire in his penthouse suite is visited by the ghost of Sarah Whitehead, the grief-stricken nun who has haunted the Bank of England for hundreds of years. What follows is a spellbinding journey through the night and around the globe as the ghost shows the billionaire the human suffering on which his excessive wealth depends. A gorgeously illustrated tale for our times with all the magic of Dickens, reminding us that love is the greatest treasure of all.
