The Land of Mist by Sir Arthur Conan Doyle

We will now leave that little group with whom we have made our first / exploration of these grey and ill-defined, but immensely important, / regions of human thought and experiences. From the researchers we will / turn to the researched. Come with me and we will visit Mr. Linden at / home, and will examine the lights and shades which make up the life of a / professional medium.

To reach him we will pass down the crowded thoroughfare of Tottenham / Court Road, where the huge furniture emporia flank the way, and we will / turn into a small street of drab houses which leads eastwards towards / the British Museum. Tullis Street is the name and 40 the number. Here it / is, one of a row, flat-faced, dull-coloured and commonplace, with railed / steps leading up to a discoloured door, and one front-room window, in / which a huge gilt-edged Bible upon a small round table reassures the / timid visitor. With the universal pass-key of imagination we open the / dingy door, pass down a dark passage and up a narrow stair. It is nearly / ten o'clock in the morning and yet it is in his bedroom that we must / seek the famous worker of miracles. The fact is that he has had, as we / have seen, an exhausting sitting the night before, and that he has to / conserve his strength in the mornings.
