Sir Arthur Conan Doyle: Tales of Terror and Mystery

Tales of Mystery 5. The Black Doctor (continued)

There were several facts which supported his innocence. It was certain that Dr. Lana was alive and in his study at half-past eleven o'clock. Mrs. Woods was prepared to swear that it was at that hour that she had heard his voice. The friends of the prisoner contended that it was probable that at that time Dr. Lana was not alone. The sound which had originally attracted the attention of the housekeeper, and her master's unusual impatience that she should leave him in peace, seemed to point to that. If this were so then it appeared to be probable that he had met his end between the moment when the housekeeper heard his voice and the time when Mrs. Madding made her first call and found it impossible to attract his attention. But if this were the time of his death, then it was certain that Mr. Arthur Morton could not be guilty, as it was AFTER this that she had met the young squire at the gate.

If this hypothesis were correct, and someone was with Dr. Lana before Mrs. Madding met Mr. Arthur Morton, then who was this someone, and what motives had he for wishing evil to the doctor? It was universally admitted that if the friends of the accused could throw light upon this, they would have gone a long way towards establishing his innocence. But in the meanwhile it was open to the public to say--as they did say--that there was no proof that anyone had been there at all except the young squire; while, on the other hand, there was ample proof that his motives in going were of a sinister kind. When Mrs. Madding called, the doctor might have retired to his room, or he might, as she thought at the time, have gone out and returned afterwards to find Mr. Arthur Morton waiting for him. Some of the supporters of the accused laid stress upon the fact that the photograph of his sister Frances, which had been removed from the doctor's room, had not been found in her brother's possession. This argument, however, did not count for much, as he had ample time before his arrest to burn it or to destroy it. As to the only positive evidence in the case--the muddy footmarks upon the floor--they were so blurred by the softness of the carpet that it was impossible to make any trustworthy deduction from them. The most that could be said was that their appearance was not inconsistent with the theory that they were made by the accused, and it was further shown that his boots were very muddy upon that night. There had been a heavy shower in the afternoon, and all boots were probably in the same condition.
