It was a strange invitation, strangely brought about. But I saw no reason for myself why I should not accept it, and I followed him into the hall. It was spacious, but sparsely furnished. The matted floor had a cold look, and so had the gaunt stand which seemed to be a fixture, and boasted but one umbrella, one sunshade, and one dog-whip. As I passed a half-open door I caught a glimpse of a small room prettily furnished, with dainty prints and water-colors on the walls. But these were of a common order. A dozen replicas of each and all might be seen in a walk through Bond Street. Even this oasis of taste and comfort told the same story as had the bare hall and dreary exterior; and laid, as it were, a finger on one's heart. I trod softly as I followed my guide along the strip of matting toward the rear of the house. He opened a door at the inner end of the hall, and led me into a large and lofty room, built out from the back, as a state dining room or ballroom. At present it rather resembled the latter, for it was without furniture. "Now," said the old man, turning and respectfully touching my sleeve to gain my attention, "now you will not consider your labor lost in coming to see that, sir. It is a portrait of the second Lord Wetherby by Sir Anthony Van Dyck, and is judged to be one of the finest specimens of his style in existence." I was lost in astonishment; amazed, almost appalled! My companion stood by my side, his face wearing a placid smile of satisfaction, his hand pointing slightly upward to the blank wall before us. The blank wall! Of any picture, there or elsewhere in the room, there was no sign. I turned to him and then from him, and I felt very sick at heart. The poor old fellow was--must be--mad. I gazed blankly at the blank wall. "By Van Dyck?" I repeated mechanically. "Yes, sir, by Van Dyck," he replied, in the most matter-of-fact tone imaginable. "So, too, is this one;" he moved, as he spoke, a few feet to his left. "The second peer's first wife in the costume of a lady-in-waiting. This portrait and the last are in as good a state of preservation as on the day they were painted." Oh, certainly mad! And yet so graphic was his manner, so crisp and realistic were his words, that I rubbed my eyes; and looked and looked again, and almost fancied that Lord Walter and Anne, his wife, grew into shape before me on the wall. Almost, but not quite; and it was with a heart full of wondering pity that I accompanied the old man, in whose manner there was no trace of wildness or excitement, round the walls; visiting in turn the Cuyp which my lord bought in Holland, the Rubens, the four Lawrences, and the Philips--a very Barmecide feast of art. I could not doubt that the old man saw the pictures. But I saw only bare walls.
