Clever, and a Christmas ghost story in the Victorian tradition, this is a fun addition to the decades-old and newly-revived A Ghost Story for Christmas anthology. Screenwriter and series producer Mark Gatiss couldn't resist writing the story's voice of reason "The Friend," as a young, pre-Baker Street Holmes, even putting a quote from Conan Doyle's Homes in the script. Solid cast, good production values and a suitably dreadful and gruesome conclusion, this is a ghost story worthy of the English tradition of telling ghost stories around the Christmas fire. The new season's episodes are all good fun.
