I wrote to Herrick that same evening and his answer came a couple of days later, saying that he hoped to get away towards the end of the month. I had said nothing in my letter about the events of the summer, but merely mentioned that the Lessings were my neighbours for the time being. Herrick wrote: "I shall be glad to meet Lessing again. He seems to have buried himself in obscurity for the last twelve months. Is he still as enthusiastic a theorist as ever, or has the country sobered his ideas? In any case you are to be congratulated on having for neighbours three of the most charming people it has ever been my luck to meet." I smiled at the "three." In my own mind I could have substituted another numeral which would explain much of Herrick's promptitude in accepting my invitation. He was very much mistaken if he thought that any such artless device would put me off the track. In imagination I already saw myself playing the rôle of a reluctant gooseberry during his visit. Lessing, when I mentioned my expected guest, made a comment almost identical with Herrick's own. "Herrick?" he said. "Good! We shall have some arguments, Haverill, that will eclipse even your own. If Herrick gets to the bottom of this by any of his cut-and-dried theories and deductions I'll give him best once and for all!" One thing at least pleased me. I gathered from both their remarks that whatever difference had occurred between them had been purely a battle of opinion, and had no influence on their fundamental regard for one another. Meantime my meeting with Mary Lessing, and the subsequent incident of the broken hand-rail, had settled my mind on one point at least. There was some malicious influence at work in the neighborhood which was distinctly and obviously human, whether it bore any relation to the laboratory experiences or not, and at any cost, even if necessary in the face of Lessing's opposition, she must be kept clear of it.
