The best episode of the series. Winks to Samuel Warren and Arthur Conan Doyle, friendly actors, and Agatha Christie who invents a kind of superhero before the Marvel. Dermot West is an ancient soldier who fought on the Mesopotamian front during the Great War and has a strange power: the red signal. The whole episode is bathed in mysticism, mysteries, all in the heart of the London fog. It's almost like a Harry Dickson adventure. This episode is well above the rest of the series. A delight.
