Mrs. Delamere, our medium, was his sister, the wife of Delamere, the rising sculptor. Our experience had shown us that to work on these subjects without a medium was as futile as for an astronomer to make observations without a telescope. On the other hand, the introduction of a paid medium was hateful to all of us. Was it not obvious that he or she would feel bound to return some result for money received, and that the temptation to fraud would be an overpowering one? No phenomena could be relied upon which were produced at a guinea an hour. But, fortunately, Moir had discovered that his sister was mediumistic--in other words, that she was a battery of that animal magnetic force which is the only form of energy which is subtle enough to be acted upon from the spiritual plane as well as from our own material one. Of course, when I say this, I do not mean to beg the question; but I am simply indicating the theories upon which we were ourselves, rightly or wrongly, explaining what we saw. The lady came, not altogether with the approval of her husband, and though she never gave indications of any very great psychic force, we were able, at least, to obtain those usual phenomena of message-tilting which are at the same time so puerile and so inexplicable. Every Sunday evening we met in Harvey Deacon’s studio at Badderly Gardens, the next house to the corner of Merton Park Road. Harvey Deacon’s imaginative work in art would prepare any one to find that he was an ardent lover of everything which was _outré_ and sensational. A certain picturesqueness in the study of the occult had been the quality which had originally attracted him to it, but his attention was speedily arrested by some of those phenomena to which I have referred, and he was coming rapidly to the conclusion that what he had looked upon as an amusing romance and an after-dinner entertainment was really a very formidable reality. He is a man with a remarkably clear and logical brain--a true descendant of his ancestor, the well-known Scotch professor--and he represented in our small circle the critical element, the man who has no prejudices, is prepared to follow facts as far as he can see them, and refuses to theorise in advance of his data. His caution annoyed Moir as much as the latter’s robust faith amused Deacon, but each in his own way was equally keen upon the matter.
