Katherine shivered.
"Half-past two. I looked at my watch. The same time as last night."
With a gesture of resolution she led the way into the corridor. Bobby shrank from the damp and musty atmosphere of the narrow pa.s.sage.
"Why do you come, Katherine?" he asked.
"I have to know, as I had to know last night."
Graham raised his hand and knocked at the door which again was locked on the inside. The echoes chattered back at them. Graham knocked again. With a pa.s.sionate revolt Katherine raised her hands, too, and pounded at the panels. Suddenly she gave up. She let her hands fall listlessly.
"It"s no use."
"Howells! Howells!" Graham called. "Why don"t you answer?"
"When he boasted to-night," Katherine whispered, "the murderer heard him."
"Suppose he"s gone down to the library?" Graham said.
Bobby gave Katherine the candle.
"No. He"d have stayed. We"ve got to break in here. We"ve got to find out."
Graham placed his powerful shoulder against the door. The lock strained. Bobby added his weight. With a splintering of wood the door flew open, precipitating them across the threshold. Through the darkness Graham sprang for the opposite door.
"It"s locked," he called, "and the key"s on this side."
Bobby took the candle from Katherine and forced himself to approach the bed. The flame flickered a little in the breeze which stole past the curtain of the open window. It shook across the body of Howells, fully clothed with his head on the stained pillow. His face, intricately lined, was as peaceful as Silas Blackburn"s had been. Its level smile persisted.
Bobby caught his breath.
"Howells--"
He set the candle on the bureau.
"It"s no use. We must look at the back of his head."
"The back of his head!" Katherine echoed.
"It"s illegal," Graham said.
"Look!" Bobby cried. "We"ve got to look!"
Graham tiptoed forward. He stretched out his hand. With a motion of abhorrence he drew it back. Bobby watched him hypnotically, thinking: "I wanted this. I hated him. I thought of it just before I went to sleep."
Graham reached out again. This time he touched Howells"s head. It rolled over on the pillow.
"Good G.o.d!" he said.
They stared at the red hole, near the base of the brain, at a fresh crimson splotch, straying beyond the edges of the darker one they had seen that afternoon.
Graham turned away, his hand still outstretched, as if it had touched some poisonous thing and might retain a contamination.
"He was prepared against it," he whispered, "expected it, yet it got him."
He glanced rapidly around the room whose shadows seemed crowding about the candle to stifle it.
"Unless we"re all mad," he cried, "the murderer must be hidden in this room now. Don"t you see? He"s got to be, or Groom"s right, and we"re fighting the dead. Go out, Katherine. Stand by that broken door, Bobby. I"m going to look."
CHAPTER IV.
A STRANGE LIGHT APPEARS AT THE DESERTED HOUSE.
Graham"s intention, logical as it was, impressed Bobby as quite futile. Silas Blackburn had died in this ancient, melancholy room behind locked doors. This afternoon, with a repet.i.tion of the sounds that had probably accompanied his death, they had been drawn to find that, behind locked doors again, the position of the body had changed incredibly, as if to expose to them the tiny fatal wound at the base of the brain. Now for the third time those stealthy movements had aroused Katherine, and they had found, once more behind locked doors, the determined and malicious detective, murdered precisely as old Blackburn had been.
Of course Graham was logical. By every rational argument the murderer must still be in the room. Yet Bobby foresaw that, as always, no one would be found, that nothing would be unearthed to explain the succession of tragic mysteries. While Graham commenced his search, indeed, he continued to stare at the little round hole in Howells"s head, at the fresh, irregular stain on the pillow, and he became absorbed in his own predicament. Again and again he asked himself if he could be responsible for these murders which had been committed with an inhuman ingenuity. He knew only that he had wandered, unconscious, in the vicinity of the Cedars last night; that he had been asleep when his grandfather"s body had altered its position; that he had gone to sleep a little while ago too profoundly, brooding over Howells"s challenge to the murderer to invade the room of death and kill him if he could. Howells had been confident that he could handle a man and so solve the riddle of how the room had been entered. Certainly Howells"s challenge had been accepted, and Bobby knew that he had fallen into that deep sleep hating the detective, telling himself that the man"s death might save him from arrest, from conviction, from an intolerable walk to a little room with a single chair.
"Recurrent aphasia." The doctor"s expression came back to him. In such a state a man could overcome locked doors, could accomplish apparent miracles and retain no recollection. And Bobby had hated and feared Howells more than he had his grandfather.
Dully he saw Katherine go out at Graham"s direction. As one in a dream he moved toward the door they had had to break down on entering.
"Stand close to it," Graham said. "We"ll cover everything."
"You"ll find no one," Bobby answered with a perfect a.s.surance.
He saw Graham take the candle and explore the large closets. He watched him examine the s.p.a.ces behind the window curtains. He could smile a little as Graham stooped, peering beneath the bed, as he moved each piece of furniture large enough to secrete a man.
"You see, Hartley, it"s no use."
Graham"s lack of success, however, stimulated his anger.
"Then," he said, "there must be some hiding place in the walls. Such devices are common in houses as old as this."
Bobby indicated the silent form of the detective.
"He believed I killed my grandfather. The only reason he didn"t arrest me was his failure to find out how the room had been entered and left. Don"t you suppose he looked for a hiding place or a secret entrance the first thing? It"s obvious."
But Graham"s savage determination increased. He sounded each panel. None gave the slightest revealing response. He got a tape from Katherine and measured the dimensions of the room, the private hall, and the corridor. At last he turned to Bobby, his anger dead, his face white and tired.
"Everything checks," he admitted. "There"s no secret room, no way in or out. Logically Groom"s right. We"re fighting the dead who resent the intrusion of your grandfather and Howells."
He laughed mirthlessly.
"After all, we can"t surrender to that. There must be another answer."
"From the first Howells was satisfied with me," Bobby said.
Graham flung up his hands.
"Then tell me how you got in without disturbing those locks. I grant you, Bobby, you had sufficient motive for both murders, but I don"t believe you have two personalities, one decent and lovable, the other cruel and cunning to the point of magic. I don"t believe if a man had two such personalities the actions of one would be totally closed to the memory of the other."
Bobby smiled wanly.
"It isn"t pleasant to confess it, Hartley, but I have read of such cases."
"Fiction!"
"Scientific fact."
"I wish to the devil I had shared your room with you to-night," Graham muttered. "I might have furnished you an alibi for this affair at least."
"Either that," Bobby answered frankly, "or you might have followed me and learned the whole secret. Honestly, isn"t that what you were thinking of, Hartley? And I did go to sleep, telling myself it would help me if something of the sort happened to Howells. Now I"m not so sure that it will. I--I suppose you"ve got to notify the police."
Graham held up his hand.
"What"s that? In the corridor!"
There were quiet footsteps in the corridor. Bobby turned quickly, Paredes strolled slowly through the pa.s.sage, a cigarette held in his slender, listless fingers. Bobby stared at him, remembering his surprise a few minutes ago that the Panamanian should have sat up so late, should have been, probably, in the court when they had followed Katherine to the discovery of this new crime.
Paredes paused in the doorway. He took in the tragic picture framed by the sinister room without displaying the slightest interest. He continued to hold his cigarette until it expired. Then he crossed the threshold. Graham and Bobby watched the expressionless face. Gracefully Paredes raised his finger and pointed to the bed. When he spoke his voice was low and pleasant: "Appalling! I feared something of the kind when I heard you come to this room."
He glanced at the broken door.
"The same unbelievable circ.u.mstance," he drawled. "I see you had to break in."
The colour flashed back to Graham"s face.
"You have taken plenty of time to solve your misgivings."
"It hasn"t been so long. I fancied everything was all right, and I was immersed in my solitaire. Then I heard a stirring upstairs. As I"ve told you, the house frightens me. It is not natural or healthy. So I came up to investigate this stirring, and there was Miss Katherine in the hall. She told me."
Graham faced him with undisguised enmity.
"Immersed in your solitaire! We were attracted by a light in the lower hall at such an hour. We looked down. You were not there. The front door was open."
Paredes glanced at his cold cigarette. He yawned.
"When Howells died precisely as Mr. Blackburn did," Graham hurried on, "you alone were awake about the house. Weren"t you at that moment in the court?"
Paredes laughed tolerantly.
"It is clear, in spite of my apologies, that we are not friends, Graham; but, may I ask, are you accusing me of this strange--accident?"
"I should like to know what you were doing in the court."
"Perhaps," Paredes answered, "I was attracted there by the sounds that aroused Miss Katherine."
Graham shook his head.
"From her description I doubt if those sounds would have been audible in the hall."
"No matter," Paredes said. "I merely suggest that it"s a case for Groom. His hint of a spiritual enmity may be saner than you think."
Katherine appeared in the doorway. She had evidently overheard Paredes"s comment, for she nodded. The determination in her eyes suggested that she had struggled with the situation during these last moments and had reached a definite conclusions That quality was in her voice.
"At least, Hartley," she said, "you must send for Doctor Groom before you notify the police."
Graham waved his hand.
"Why?" he asked. "The man is dead."
With a movement, hidden from Paredes, she indicated Bobby.
"Last time there was a good deal of delay before the doctor came. If we get him right away he may be able to do something for this poor fellow. At least his advice would be useful."
Bobby realized that she was fighting for time for him. Any delay would be useful that would give them a chance to plan before the police with unimaginative efficiency should invade the house and limit their opportunities. Graham showed that he caught her point.
"Maybe it"s better," he said. "Then, Bobby, telephone Groom to be ready for you, and take my runabout. It"s in the stable. You"ll get him here much faster than he could come in his carriage."
"While I"m gone," Bobby asked, "what will you do?"
"Watch this room," Graham jerked out. "See that no one enters or leaves it, or touches the body. I"ll hope for some clue."
"You"ve plenty of courage," Paredes drawled. "I shouldn"t care to watch alone in this room."
He followed Katherine into the corridor. Bobby looked at Graham.
"You"ll take no chances, Hartley?"
Graham"s smile wasn"t pleasant.
"According to you and the dead detective there"s no risk while you"re out of the house. Still, I shall be nervous, but don"t worry."
Bobby joined the others before they had reached the hall.
"Of course Hartley found nothing," Katherine said to him.
"Nothing," Paredes answered, "except a very bad temper."
Katherine"s distaste for the man was no longer veiled.
