"On his back!" Robinson echoed. "But he isn"t on his back."
The doctor told of the amazing alteration in the positions of both victims. Bobby regretted with all his heart that he had made the attempt to get the evidence. Already complete frankness was impossible for him. Already a feeling of guilt sprang from the necessity of withholding the first-hand testimony which he alone could give.
"And a woman cried!" Robinson said, bewildered. "All this sounds like a ghost story."
"You"ve more sense than I thought," Doctor Groom said dryly. "I never could get Howells to see it that way."
"What are you driving at?" Robinson snapped.
"These crimes," the doctor answered, "have all the elements of a ghostly impulse."
Robinson"s laugh was a little uncomfortable.
"The Cedars is a nice place for spooks, but it won"t do. I"ll be frank. Howells telephoned me. He had found plenty of evidence of human interference. It"s evident in both cases that the murderer came back and disturbed the bodies for some special purpose. I don"t know what it was the first time, but it"s simple to understand the last. The murderer came for evidence Howells had on his person."
Bobby couldn"t meet the sharp, puffy eyes. He alone was capable of testifying that the evidence had been removed as if to secrete it from his unlawful hand. Yet if he spoke he would prove the district attorney"s point. He would condemn himself.
"Curious," Graham said slowly, "that the murderer didn"t take the evidence when he killed his man."
"I don"t know about that," Robinson said, "but I know Howells had evidence on his person. You through, Coroner? Then we"ll have a look, although it"s little use."
He walked to the bed and searched Howells"s pockets.
"Just as I thought. Nothing. He told me he was preparing a report. If he didn"t mail it, that was stolen with the rest of the stuff. Rawlins"s right. He waited too long to make his arrest."
Again Bobby wondered if the man would bring matters to a head now. He could appreciate, however, that Robinson, with nothing to go on but Howells"s telephoned suspicions, might spoil his chances of a solution by acting too hastily. Rawlins strolled in.
"The two women were asleep," he said. "The old man knows nothing beyond the fact that he heard a woman crying outside a little while ago."
"I don"t think we need bother about the back part of the house for the present," Robinson said. "Howells"s evidence has been stolen. It"s your job to find it unless it"s been destroyed. Your other job is to discover the instrument that caused death in both cases. Then maybe our worthy doctor will desert his ghosts. Mr. Blackburn, if you will come with me there"s a slight possibility of checking up some of the evidence of which Howells spoke. Our fine fellow may have made a slip in the court."
Bobby understood and was afraid--more afraid than he had been at any time since he had overheard Howells catalogue his case to Graham in the library. Why, even in so much confusion, had Graham and he failed to think of those tell-tale marks in the court? They had been intact when he had stood there just before dark. It was unlikely any one had walked across the gra.s.s since. He saw Graham"s elaborate precautions demolished, the case against him stronger than it had been before Howells"s murder. Graham"s face revealed the same helpless comprehension. They followed Robinson downstairs. Graham made a gesture of surrender. Bobby glanced at Paredes who alone had remained below. The Panamanian smoked and lounged in the easy chair. His eyes seemed restless.
"I shall wish to ask you some questions in a few minutes, Mr. Paredes," the district attorney said.
"At your service, I"m sure," Paredes drawled.
He watched them until they had entered the court and closed the door. The chill dampness of the court infected Bobby as it had always done. It was a proper setting for his accusation and arrest. For Robinson, he knew, wouldn"t wait as Howells had done to solve the mystery of the locked doors.
Robinson, while the others grouped themselves about him, took a flashlight from his pocket and pressed the control. The brilliant cylinder of light illuminated the gra.s.s, making it seem unnaturally green. Bobby braced himself for the inevitable denouement. Then, while Robinson exclaimed angrily, his eyes widened, his heart beat rapidly with a vast and wondering relief. For the marks he remembered so clearly had been obliterated with painstaking thoroughness, and at first the slate seemed perfectly clean. He was sure his unknown friend had avoided leaving any trace of his own. Each step in the gra.s.s had been carefully sc.r.a.ped out. In the confusion of the path there was nothing to be learned.
The genuine surprise of Bobby"s exclamation turned Robinson to him with a look of doubt.
"You acknowledge these footmarks were here, Mr. Blackburn?"
"Certainly," Bobby answered. "I saw them myself just before dark. I knew Howells ridiculously connected them with the murderer."
"You made a good job of it when you trampled, them out," Robinson hazarded.
But it was clear Bobby"s amazement had not been lost on him.
"Or," he went on, "this foreigner who advertises himself as your friend! He was in the court tonight. We know that."
Suddenly he stooped, and Bobby got on his knees beside him. The cylinder of light held in its centre one mark, clear and distinct in the trampled gra.s.s, and with a warm grat.i.tude, a swift apprehension, Bobby thought of Katherine. For the mark in the gra.s.s had been made by the heel of a woman"s shoe.
"Not the foreigner then," Robinson mused, "not yourself, Blackburn, but a woman, a devoted woman. That"s something to get after."
"And if she lies, the impression of the heel will give her away," the coroner suggested.
Robinson grinned.
"You"d make a rotten detective, Coroner. Women"s heels are cut to a pattern. There are thousands of shoes whose heels would fit this impression. We need the sole for identification, and that she hasn"t left us. But she"s done one favour. She"s advertised herself as a woman, and there are just three women in the house. One of those committed this serious offence, and the inference is obvious."
Before Bobby could protest, the doctor broke in with his throaty rumble: "One of those, or the woman who cried about the house."
Bobby started. The memory of that eerie grief was still uncomfortable in his brain. Could there have been actually a woman at the stagnant lake that afternoon and close to the house to-night--some mysterious friend who a.s.sumed grave risks in his service? He recognized Robinson"s logic. Unless there were something in that far-fetched theory, Katherine faced a situation nearly as serious as his own. Robinson straightened. At the same moment the sc.r.a.ping of a window reached them. Bobby glanced at the newer wing. Katherine leaned from her window. The coincidence disturbed him. In Robinson"s mind, he knew, her anxiety would a.s.sume a colour of guilt. Her voice, moreover, was too uncertain, too full of misgivings: "What is going on down there? There have been no--no more tragedies?"
"Would you mind joining us for a moment?" Robinson asked.
She drew back. The curtain fell over her lighted window. The darkness of the court was disturbed again only by the limited radiance of the flashlight. She came hurriedly from the front door.
"I saw you gathered here. I heard you talking. I wondered."
"You knew there were footprints in this court," Robinson said harshly, "that Howells connected them with the murderer of your uncle."
"Yes," she answered simply.
"Why then," he asked, "did you attempt to obliterate them?"
She laughed.
"What do you mean? I didn"t. I haven"t been out of the house since just after luncheon."
"Can you prove that?"
"It needs no proof. I tell you so."
The flashlight exposed the ugly confidence of Robinson"s smile.
"I am sorry to suggest the need of corroboration."
"You doubt my word?" she flashed.
"A woman," he answered, "has obliterated valuable testimony, I shall make it my business to punish her."
She laughed again. Without another word she turned and reentered the house. Robinson"s oath was audible to the others.
"We can"t put up with that sort of thing, sir," Rawlins said.
"I ought to place this entire household under arrest," Robinson muttered.
"As a lawyer," Graham said easily, "I should think with your lack of evidence it might be asking for trouble. There is Paredes who acknowledges he was in the court."
"All right. I"ll see what he"s got to say."
He started for the house. Bobby lingered for a moment with Graham.
"Do you know anything about this, Hartley?"
"Nothing," Graham whispered.
"Then you don"t think Katherine--"
"If she"d done it she"d have taken good care not to be so curious. I doubt if it was Katherine."
They followed the others into the hall. Bobby, scarcely appreciating why at first, realized there had been a change there. Then he understood: Robinson faced an empty chair. The hall was pungent with cigarette smoke, but Paredes had gone.
Robinson pointed to the stairs.
"Get him down," he said to Rawlins.
"He wouldn"t have gone to bed," Graham suggested. "Suppose he"s in the old room where Howells lies?"
But Rawlins found him nowhere upstairs. With an increasing excitement Robinson joined the search. They went through the entire house. Paredes was no longer there. He had, to all appearances, put a period to his unwelcome visit. He had definitely disappeared from the Cedars.
His most likely exit was through the kitchen door which was unlocked, but Jenkins who had returned to his room had heard no one. With their electric lamps Robinson and Rawlins ferreted about the rear entrance for traces. The path there was as trampled and useless as the one in front. Rawlins, who had gone some distance from the house, straightened with a satisfied exclamation. The others joined him.
"Here"s where he left the path right enough," he said. "And our foreigner wasn"t making any more noise than he had to."
He flashed his lamp on a fresh footprint in the soft soil at the side of the path. The mark of the toe was deep and firm. The impression of the heel was very light. Paredes, it was clear, had walked from the house on tiptoe.
"Follow on," Robinson commanded. "I told this fellow I wanted to question him. I"ve scared him off."
Keeping his light on the ground, Rawlins led the way across the clearing. The trail was simple enough to follow. Each of the Panamanian"s footprints was distinct. Each had that peculiarity that suggested the stealth of his progress.
As they continued Bobby responded to an excited premonition. He sensed the destination of the chase. He could picture Paredes now in the loneliest portion of the woods, for the trail unquestionably pointed to the path he had taken that afternoon toward the stagnant lake.
"Hartley!" he said. "Paredes left the house to go to the stagnant lake where I fancied I saw a woman in black. Do you see? And he didn"t hear the crying of a woman a little while ago, and when we told him he became restless. He wandered about the hall talking of ghosts."
"A rendezvous!" Graham answered. "He may have been waiting for just that. The crying may have been a signal. Perhaps you"ll believe now, Bobby, that the man has had an underhanded purpose in staying here."
"I"ve made too many hasty judgments in my life, Hartley. I"ll go slow on this. I"ll wait until we see what we find at the lake."
Rawlins snapped off his light. The little party paused at the black entrance of the path into the thicket.
"He"s buried himself in the woods," Rawlins said.
They crowded instinctively closer in the sudden darkness. A brisk wind had sprung up. It rattled among the trees, and set the dead leaves in gentle, rustling motion. It suggested to Bobby the picture which had been forced into his brain the night of his grandfather"s death. The moon now possessed less light, but it reminded him again of a drowning face, and through the darkness he could fancy the trees straining in the wind like puny men. Abruptly the thought of penetrating the forest became frightening. The silent loneliness of the stagnant lake seemed as unfriendly and threatening as the melancholy of the old room.
"There are too many of us," Robinson was saying. "You"d better go on alone, Rawlins, and don"t take any chances. I"ve got to have this man. You understand? I think he knows things worth while."
The rising wind laughed at his whisper. The detective flashed his lamp once, shut it off again, and stepped into the close embrace of the thicket.
Suddenly Bobby grasped Graham"s arm. The little group became tense, breathless. For across the wind with a diffused quality, a lack of direction, vibrated to them again the faint and mournful grief of a woman.
CHAPTER VI.
THE ONE WHO CREPT IN THE PRIVATE STAIRCASE.
The odd, mournful crying lost itself in the restless lament of the wind. The thicket from which it had seemed to issue a.s.sumed in the pallid moonlight a new unfriendliness. Instinctively the six men moved closer together. The coroner"s thin tones expressed his alarm: "What the devil was that? I don"t really believe there could be a woman around here."
"A queer one!" the detective grunted.
The district attorney questioned Bobby and Graham.
"That"s the voice you heard from the house?"
Graham nodded.
"Perhaps not so far away."
Doctor Groom, hitherto more captured than any of them by the imminence of a spiritual responsibility for the mystery of the Cedars, was the first now to reach for a rational explanation of this new phase.
"We mustn"t let our fancies run away with us. The coroner"s right for once. No excuse for a woman hiding in that thicket. A bird, maybe, or some animal--"
"Sounded more like a human being," Robinson objected.
The detective reasoned in a steady unmoved voice: "Only a mad woman would wander through the woods, crying like that without a special purpose. This man Paredes has left the house and come through here. I"d guess it was a signal."
"Graham and I had thought of that," Bobby said.
"Howells was a sharp one," Robinson mused, "but he must have gone wrong on this fellow. He "phoned me the man knew nothing. Spoke of him as a foreigner who lolled around smoking cigarettes and trying to make a fool of him with a lot of talk about ghosts."
"Howells," Graham said, "misjudged the case from the start. He wasn"t to blame, but his mistake cost him his life."
Robinson didn"t answer. Bobby saw that the man had discarded his intolerant temper. From that change he drew a new hope. He accepted it as the beginning of fulfilment of his prophecy last night that an accident to Howells and the entrance of a new man into the case would give him a fighting chance. It was clearly Paredes at the moment who filled the district attorney"s mind.
"Go after him," he said shortly to Rawlins. "If you can get away with it bring him back and whoever you find with him."
Rawlins hesitated.
