“After all that had happened, life at Kintilloch became inexpressibly painful for me and I began to look out for another job. Then I heard that the principal doctor of this little town was old and in failing health, and there was a possible opening for a new-comer. I resigned the Ransome job and set up my plate here. But every week I sent two treasury notes to Roper.
“Some fifteen or sixteen months ago, when I had been here between three and four years, I had a letter from Roper saying that he had seen an advertisement for a man and wife to act as servants to a Mr. Averill of Starvel in my neighbourhood. As he had shortly before left the Ransome he wished to apply. As a matter of fact, I found out later that he had been dismissed for drugging a patient. I forgot to say also that he had married my former servant. If, he went on, I would use my influence with Mr. Averill to get him the job he would cease his demand for the two pounds a week and send me the note he had forged.
“Mr. Averill was by this time my patient, and I mentioned Roper to him. I could do so with a clear conscience for with all his faults Roper was an excellent attendant. His wife, Flora, also was a good servant and I believed they would suit Mr. Averill well. At the same time I told Mr. Averill just why he had left the Ransome. But Mr. Averill thought that for that very reason he could get them cheap and after some negotiations they were engaged.
“The very same week Roper called on me and said I had kept my word in the past and he would keep his now. He said he was tired of crooked going and wished to live straight. He would blackmail me no longer. He handed me the forged note and watched me put it in the fire. I ceased paying him the money. From then to the day of his death he was civil when we met, and no unpleasant subjects were touched on. I began to believe his reformation was genuine, but now since you show me this I see he was unchanged. It is evident he must have made a copy of his forgery and kept one while he let me destroy the other. I wish you would tell me how you got it. What his motive can have been you may be able to guess, but I cannot.
“That, Inspector, is the whole truth of this unhappy affair. I had hoped never to have to speak of it again, and now that I have told you of it I trust that the whole miserable business may be decently buried and forgotten.”
French nodded gravely. He was puzzled by this long story of the doctor’s. The tale was certainly possible. As he reviewed each point he had to admit that not only was it possible, but it was even reasonably probable. Given a man of weak character as this doctor appeared to be, and a clever and unscrupulous ruffian, as Roper had been painted, the whole affair could have happened quite naturally and logically. Moreover it adequately covered all the facts.
On the other hand, if Philpot had killed his wife he would tell just some such tale as this. There was no one to refute it. Roper and his wife were dead and the nurse had left the country. Of course, it might be possible to trace the nurse, but it certainly couldn’t be done easily or rapidly.
As he turned the matter over in his mind it seemed to French that the crucial point was the authenticity of the confession. If Philpot had written it, he had done so because he was guilty and because he, therefore, could not help himself. However terrible the putting of such a statement in black and white would be to him, it would be the lesser of two evils, the alternative being immediate betrayal. But if the confession were a forgery all this would be reversed. It could only have come into being in some such way as the doctor had described. In fact, in his case it would amount to a powerful confirmation of his story.
Now, upon this point there was no doubt. The confession definitely was a forgery. The Yard experts were unanimous, and their opinion under such circumstances might be taken for gospel. French might therefore start with a strong bias in favour of Philpot.
This French realised, and then he found himself again weighed down by doubt. Was it credible that a man would really pay blackmail for fear of having an obviously forged confession produced? At first French did not think so—he would not have done it himself—but as he considered the special circumstances he saw that this question did not accurately describe the situation as it would appear to the doctor. In the first place, Philpot did not know how bad a forgery the document was. It seemed to him his own writing, and he had no guarantee that it would not be accepted as such. But he knew that if it were produced he would almost certainly have the misery of arrest and imprisonment and possibly of trial also. Moreover, the episode of the nurse would come out, and the result of the whole business would have been ruin to his career. If Philpot had been a strong man he would no doubt have faced the situation, but as it was, French felt sure that he would take the coward’s way. No, there was nothing in this idea to make him doubt the man’s story.
