The manuscript enclosed was, of course, from Sir Robert himself. It was in the form of a letter to young Grenfell; and after explaining that he thought it better to write to him, not having my address, he plunged into the real object of his communication. "You will not," he said, "have forgotten the incident of the 'ghost-cup,' in the summer of last year, and the curious story your friend was so good as to tell us about it. You may remember--Mrs. ---- will, I am sure, do so--my strong impression that I had recently seen one like it. After I left you I could not get this feeling out of my head. It is always irritating not to be able, figuratively speaking, 'to lay your hand' on a recollection, and in this instance I really wanted to get the clue, as it might lead to some sort of 'explanation' of the little girl's strange experience. I cudgelled my brains, but all to no purpose; I went over in memory all the houses at which I had visited within a certain space of time; I made lists of all the people I knew interested in 'china,' ancient or modern, and likely to possess specimens of it. But all in vain. All I got for my pains was that people began to think I was developing a new crotchet, or, as I heard one lady say to another, not knowing I was within earshot, 'the poor man must be a little off his head, though till now I have always denied it. But the revulsion from benevolent schemes to china-collecting shows it only too plainly.' So I thought I had better leave off cross-questioning my 'collecting' friends about porcelain and faience, German ware in particular. And after a while I thought no more about it. Two months ago I had occasion to make a journey to the north--the same journey and to stay at the same house where I have been four or five times since I saw the 'ghost-cup.' But this was what happened _this_ time. There is a junction by which one must pass on this journey. I generally manage to suit my trains so as to avoid waiting there, but this is not always feasible. This time I found that an hour at the junction was inevitable. There is a very good refreshment room there, kept by very civil, decent people. They knew me by sight, and after I had had a cup of tea they proposed to me, as they have done before, to wait in their little parlour just off the public room. 'It would be quieter and more comfortable,' said either the mother or the daughter who manage the concern. I thanked them, and settled myself in an arm-chair with my book, when, looking up--there on the mantelpiece stood the fellow cup--the identical shape, pattern, and colour! It all flashed into my mind then. I had made this journey just before going into your neighbourhood last year, and had waited in this little parlour just as this time. "'Where did you get that cup, Mrs. Smith?' I asked. "There were two or three rather pretty bits of china about. The good woman was pleased at my noticing it.
