Imagine my surprise when they rang again. I flung the door open, and was about to ask them what they meant by their impudence, when one of the little group upon my doorstep said, "If you please, sir, it's the baby." Never was there such a change--from the outraged householder to the professional man. "Pray step in, madam," said I, in quite my most courtly style; and in they all came--the husband, the brother, the wife and the baby. The latter was in the early stage of measles. They were poor outcast sort of people, and seemed not to have sixpence among them; so my demands for a fee at the end of the consultation ended first in my giving the medicine for nothing, and finally adding fivepence in coppers, which was all the small change I had. A few more such patients and I am a broken man.
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.
But a blacker depth of treachery lay beyond. If he had read them, and if he had been insane enough to think that I was acting disloyally towards him, why had he not said so at the time? Why had he contented himself with sidelong scowls and quarrelling over trivialities-- breaking, too, into forced smiles when I had asked him point blank what was the matter? One obvious reason was that he could not tell his grievance without telling also how he had acquired his information. But I knew enough of Cullingworth's resource to feel that he could easily have got over such a difficulty as that. In fact, in this last letter he HAD got over it by his tale about the grate and the maid. He must have had some stronger reason for restraint. As I thought over the course of our relations I was convinced that his scheme was to lure me on by promises until I had committed myself, and then to abandon me, so that I should myself have no resource but to compound with my creditors- to be, in fact, that which my mother had called him.
