However, the two incidents together had the effect of taking up my attention and breaking the blow which I had had in the Cullingworth letter. It made me laugh to think that the apparent outsider should prove to be a patient, and the apparent patient an outsider. So back I went, in a much more judicial frame of mind, to read that precious document over again, and to make up my mind what it was that I should do. And now I came to my first real insight into the depths which lie in the character of Cullingworth. I began by trying to recall how I could have torn up my mother’s letters, for it is not usual for me to destroy papers in this manner. I have often been chaffed about the way in which I allow them to accumulate until my pockets become unbearable. The more I thought about it the more convinced I was that I could not have done anything of the sort; so finally I got out the little house jacket which I had usually worn at Bradfield, and I examined the sheaves of letters which it contained. It was there, Bertie! Almost the very first one that I opened was the identical one from which Cullingworth was quoting in which my mother had described him in those rather forcible terms. Well, this made me sit down and gasp. I am, I think, one of the most unsuspicious men upon earth, and through a certain easy-going indolence of disposition I never even think of the possibility of those with whom I am brought in contact trying to deceive me. It does not occur to me. But let me once get on that line of thought--let me have proof that there is reason for suspicion--and then all faith slips completely away from me. Now I could see an explanation for much which had puzzled me at Bradfield. Those sudden fits of ill temper, the occasional ill-concealed animosity of Cullingworth--did they not mark the arrival of each of my mother’s letters? I was convinced that they did. He had read them then--read them from the pockets of the little house coat which I used to leave carelessly in the hall when I put on my professional one to go out. I could remember, for example, how at the end of his illness his manner had suddenly changed on the very day when that final letter of my mother’s had arrived. Yes, it was certain that he had read them from the beginning.
