She departed without another word, leaving Wilfrid to do what he could with her uncle. This second attack was much more serious than the first, for Samuel Flower lay to all appearance dead. It was not difficult for Wilfrid to make an examination, for Flower had undressed and gone to bed before the attack. He lay on his back with his arms inert by his side, the deep purple of his cheeks had given way to a ghastly whiteness. Wilfrid could detect not the slightest trace of violence anywhere, nothing but one or two small indentations on the forehead and at the back of the head. Try as he would Wilfrid could make nothing of the case. And if he could trust to his trained knowledge, he felt sure that no explanation would ever come from Flower's lips, for surely the man was dead.
He could hear no murmur from the heart. By laying the glass of his watch on the murdered man's lips he could distinguish no moisture. He could only wait patiently until assistance came, and then tell the story as best he could. With almost a sensation of shame Wilfrid realized that Flower was harmless to do him further injury. He tried to put the matter out of his mind, but it recurred more than once, until he was fain to walk up and down the room in the growing light. He pulled up the blinds by and by and let in the flood of day. Even in the strong light he could detect no motion and no change in that awful figure on the bed. Inured as he was to these kind of tragedies, it was with a thrill of thankfulness that he heard steps coming up the stairs and saw a stranger enter the room. There was no reason for Wilfrid to ask if the new-comer were a doctor, for he carried his profession in every crease of his well-fitting frock-coat, in every line of his well-groomed hair.
"My name is Dr. Shelton," he said. "I am sorry to be so late, but I have only just got back to town. So this is your patient? What do you think he is suffering from? You have made an examination?"
"I haven't the remotest idea," Wilfrid said frankly. "I have never seen a case like it before. Mr. Flower lies there to all appearances dead. He does not breathe. There is not the slightest motion of the heart, and yet, rigor mortis has not set in. I should say it is some brain trouble."
Dr. Shelton stripped off his coat and turned up his shirt sleeves. For a long time he bent over the bed, but at last he stood upright drawing a long breath.
"Most extraordinary," he murmured. "Everything points to severe concussion of the brain, and yet there is not the slightest trace of violence; there is no suggestion of a blow, or fall, or anything of that kind. We must wait till the patient comes to himself as he will before long."
"He is not dead, then?" Wilfrid asked.
"No. It is a case of suspended animation. That the brain is seriously injured the congestion of the eyes proves beyond demonstration. But, surely, you can throw some light on this mystery. How came you to be called in?"
Wilfrid had been dreading the question for some time. He hardly knew how to explain matters to this polished man of the world whose lines had probably always fallen in conventional places.
"Well, it was like this," he began. "I have lately started a practice in Oldborough and Mr. Flower has a country house close by. I was called in to attend him for a trifling injury, and when I got to the house I discovered that Miss Galloway, Mr. Flower's niece, was an old friend; in fact, we had met in London some months ago. Miss Galloway had been under the impression that some one was trying to get into the house, but perhaps I had better tell you at length what really happened."
