The Christmas Tree Murders

December 1883. Inventor and millionaire Sir Russell Morgan has invited his friends and investors to celebrate Christmas at Clifftop House. But when a footman is found dead - electrocuted - on the very first night of the party, festivities are thrown to the wind. The police dismiss Fred's death as an accident, but his friend Millie, the kitchenmaid, is not so sure.
Who would have wanted to kill Fred? Did he know a secret about the Morgan family? Or about Sir Russell's guests?
Christmas Day comes, and with it another dead body.
Can the killer be caught before they strike again?
