The mysterious Mr. Quin

A conjurer of skill with an instinct for detection, Mr. Harley Quin has an almost magical flair for appearing at the scene of the most remarkable crimes. But is it just a trick of light that haunts his shadow with a ghostly apparition? Is it fate that invites him to a New Year's murder? And what forces are at work when his car breaks down outside Royalston Hall, an isolated estate with a deadly history? It was a typical New Year's Eve house party until a mysterious stranger arrived after midnight. Who was this Mr Quin and why did his presence have such a profound effect on Eleanor Portal, the woman with the dyed-black hair?
