Not content with a casual inspection, he particularly examined those papers which, in his dream adventure, he had believed to have been submitted to mysterious inspection. They showed no signs of having been touched. The casement curtains were drawn across the recess formed by the French windows, and sunlight streamed in where, silhouetted against the pallid illumination of the moon, he had seen the man in the cowl. Drawing back the curtains, he examined the window fastenings. They were secure. If the window had really been open in the night, he must have left it so himself. "Well," muttered Stuart--"of all the amazing nightmares!" He determined, immediately he had bathed and completed his toilet, to write an account of the dream for the Psychical Research Society, in whose work he was interested. Half an hour later, as the movements of an awakened household began to proclaim themselves, he sat down at his writing-table and commenced to write. Keppel Stuart was a dark, good-looking man of about thirty-two, an easy-going bachelor who, whilst not over ambitious, was nevertheless a brilliant physician. He had worked for the Liverpool School of Tropical Medicine and had spent several years in India studying snake poisons. His purchase of this humdrum suburban practice had been dictated by a desire to make a home for a girl who at the eleventh hour had declined to share it. Two years had elapsed since then, but the shadow still lay upon Stuart's life, its influence being revealed in a certain apathy, almost indifference, which characterised his professional conduct. His account of the dream completed, he put the paper into a pigeon-hole and forgot all about the matter. That day seemed to be more than usually dull and the hours to drag wearily on. He was conscious of a sort of suspense. He was waiting for something, or for someone. He did not choose to analyse this mental condition. Had he done so, the explanation was simple--and one that he dared not face. At about ten o'clock that night, having been called out to a case, he returned to his house, walking straight into the study as was his custom and casting a light Burberry with a soft hat upon the sofa beside his stick and bag. The lamps were lighted, and the book-lined room, indicative of a studious and not over-wealthy bachelor, looked cheerful enough with the firelight dancing on the furniture. Mrs. M'Gregor, a grey-haired Scotch lady, attired with scrupulous neatness, was tending the fire at the moment, and hearing Stuart come in she turned and glanced at him. "A fire is rather superfluous to-night, Mrs. M'Gregor," he said. "I found it unpleasantly warm walking."
