I felt, like my wife, that it was a matter of waiting for what would turn up. In the neighbourhood of the murder there was probably very little to turn up. The police, I felt no doubt, had made all manner of enquiries; and as for anything that I was likely to pick up, I supposed I had already heard all, and more than all that any person in the neighbourhood knew about the matter. I may anticipate a little and say that in the whole of the four months, which, as it proved, were all that remained to me as Rector of Long Wilton, no fresh information was given to me by my neighbours there. It soon occurred to me that the murder of Longhurst, far away and long ago, might be easier to trace than the recent, but perhaps more carefully veiled, crime committed to cover it. Peters, I reasoned, must have been in possession of proofs of it, and probably, as I searched his voluminous papers, something would appear to indicate the nature of those proofs. I began, as in any case I should have done, a careful reading of his papers. It took up no small part of my spare time, for I found that he had prepared little enough for immediate publication, but fuller and more valuable materials for his projected book of psychology than I should at all have expected from his manner of proceeding. But, of what now interested me more than my friend’s philosophy, I found nothing in all this mass of letters and notes and journals; nothing, that is, which threw direct light on this mystery, for indeed his psychological notes and my discussions with a friend of his, an Oxford philosophy tutor, to whom I eventually committed them, did, I think, influence me not a little in one important part of my enquiry later.
In pushing enquiries further afield there was need for some caution. An indiscretion might have brought what I was doing unnecessarily soon to the notice of the suspected man, and the great ability with which I credited him might suggest some effective scheme for baffling my search. But of course I wrote early to Mr. Bryanston to ask if he would tell me to whom he alluded as “C.,” whether Longhurst was the man whom Peters suspected had been murdered, and whether I inferred rightly that “C.” was involved in this suspicion.
It was my duty to put all that I knew at the disposal of the police, and the opportunity for doing so soon presented itself in the visit, which, as I have said, was paid to me to enquire about Callaghan. My visitor was an important official, since dead, whom I need not more clearly indicate. He had been a military man, and he struck me as, in some ways, admirably qualified for his post. He was, I believe, excellent in the discipline he maintained among his subordinates and in all the dispositions he made for meeting the common public requirements. I am told also that he had wonderful familiarity with the ways of ordinary lawbreakers, but he did not appear to me to have much elasticity of mind. After answering fully his question about Callaghan, I thought it right to give my own impression of his innocence. My visitor answered me with a somewhat mysterious reference to those who really guided the conduct of the affair. He could not himself, he said, go behind their views. Then with an evident sympathy for my concern about Callaghan, he told me in confidence and still more mysteriously that the opinion of an eminent specialist had been taken.
I then ventured to press the question of Trethewy’s release, and learnt that it was being carefully considered, but he could not be set free immediately. Then I told my visitor of the statement of Vane-Cartwright when Callaghan first spoke of Trethewy, and how Trethewy’s confession proved this to have been a deliberate falsehood. I showed him and gave him copies of the letters of Bryanston to Peters and to me. I informed him, and at my request he noted, that Vane-Cartwright had opened the first letter. I stated what I had myself observed of Vane-Cartwright’s conduct, and indicated frankly the conclusion which I was disposed to draw. It did not seem to me that I produced any impression. My visitor listened, if I may say so, with the air of a man who completely takes in the fact and sees that it should be put in some pigeonhole, but is without either apprehension or wonder as to its real bearing. I gathered, on the whole, that the official mind was chiefly taken up with the theory that Callaghan
