"That remains to be seen," Robinson sneered as soon as she had gone. "Now, Mr. Paredes."
"I"ve really told you everything," he said. "I walked toward the graveyard. At a point very close to it I felt the presence of this creature in black. I spoke. I took my courage in my hands. I reached out. I touched nothing." He raised his injured hand. "I got this for my pains."
"What made you go to the graveyard?" Robinson asked suspiciously.
There was no mockery in the Panamanian"s answer.
"I have told you the court for me has always been full of ghosts." He pointed to Silas Blackburn. "It frightened me that this man should come back through the court from his grave with all the evidence pointing to an astral magic. I wanted to retrace his journey. I thought at the grave, if I were alone, something might expose itself that had naturally remained hidden in the presence of so many materialistic human beings."
A smile spread over Rawlins"s cold, unimaginative features.
"That sounds well, Mr. Paredes, and there is a lot about this case that looks like ghosts, but leave us a few flesh-and-blood clues. This woman in black is one of them, although she"s been slippery as an eel. It looks to me as if you went to the grave to meet her alone exactly as you went to the deserted house to talk quietly with her night before last. Maybe she mistook you for one of us snooping in the dark, and let you have it."
"If that is so," Paredes said easily, "the nature of my wound would suggest that she is guilty of the crimes in the old room. Why not go out and arrest her then? She might explain everything except the return to life of Mr. Blackburn. I"m afraid that"s rather beyond you in any case. But at least find her."
Robinson joined in Rawlins"s laugh.
"Why go outside for that?"
Paredes started.
"You never mean--"
"You bet we do," Rawlins said. "If what I"ve doped out hadn"t been so we"d have caught her long before. We"re not blind, and we haven"t missed the nerve with which she helped the doctor fix you up. We haven"t caught her before because her headquarters have been right in this house all the time. You remember the other night, Mr. Robinson. You"d just questioned her in the court and had threatened to question him, too, when she came in here ahead of us and slipped out the back way. She must have told him to follow because they had to talk, undisturbed by us. They went by different roads to the deserted house where a light had been seen before. We happened to hit his trail first and followed it. I"ll guarantee you didn"t see her when you first came in."
Robinson shook his head.
"Mr. Graham kept me busy, and I rather waited for your report before pushing things. I didn"t see her or question her until after Mr. Graham and Mr. Blackburn had started for New York."
"And she could have sneaked in the back way any time before that," Rawlins said.
"It"s utter nonsense!" Graham cried.
Rawlins turned on him.
"See here, Mr. Graham, you"ve been trying to fight me off this way all afternoon. It won"t do."
"Katy"s a good girl," Silas Blackburn quavered.
With a growing discomfort Bobby realized that when the woman had cried near the graveyard he had reached out for Katherine and had failed to find her. Moreover, the night Graham and he had heard the crying in the old room she had stood alone in the corridor. It was easily conceivable that the turn of events after Robinson"s arrival should have made it necessary for conspirators to consult free from any danger of disturbance. But Katherine, he told himself, was a.s.suredly the victim of coincidence. He couldn"t picture her entangled in any of Paredes"s purposes. Her dislike of the man was complete and open. But he saw that Rawlins out of the ma.s.s of apparently inexplicable clues had extracted this material one and would follow it desperately no matter who was hurt; and Robinson was behind him. That accounted for their frequent excursions upstairs during the afternoon, for Rawlins"s ascent as soon as they had returned from the grave. They had evidently found something to sharpen their suspicions, and Graham probably knew what it was.
Robinson took out his watch.
"We can"t put this off too late," he mused.
The detective at his heels, he walked to the library. Bobby started after them. Graham caught him and they crossed the dining room together.
"What do they mean to do?" Bobby asked.
"I have been afraid of it since this afternoon," Graham answered. "I haven"t cared to talk about it. I had hoped to hold them off. They intend to search Katherine"s room. I think they believe she has something important hidden there. I"ve been wondering if they"ve got track of Howells"s report which we told Jenkins to hide."
"Why," Bobby asked, "should that involve Katherine?"
"Howells may have written something damaging to her. He knew she was devoted to your interests."
Robinson called to them from the library.
"Won"t you please come in, Mr. Blackburn?"
Bobby and Graham continued to the library. They found Rawlins gazing through the door of the private staircase.
"We could go up this way," he was saying, "and across the old room so that she needn"t suspect."
"What is he talking about?" Bobby asked Robinson angrily.
"You wanted to help," Robinson answered, "so Rawlins and I are going to give you a chance. We are about to search your cousin"s room. We hope to find there an explanation of a part of the mystery--the motive, at least, for Howells"s death; perhaps your own exoneration. You"d do anything to have that, wouldn"t you? You"ve said so."
"At her expense!" Bobby cried. "You"ve no right to go to her room. She"s incapable of a share in such crimes. Do you seriously think she could plan an escape from the grave and bring back to life a man three days dead?"
"Give me a human being that caused death," Robinson answered, "and I"ll tackle the ghosts later. You"re wrong if you think I"m going to quit cold because your grandfather looks like a dead thing that moves about and talks. I shan"t give up to that madness until I"ve done everything in my power. I would be a criminal myself if I failed to do as Rawlins wishes. If your cousin"s skirts are clear no harm will be done. I"m acting on the a.s.sumption that your confession was honest. I want you to get Miss Perrine out of her room. I want you to see that she stays downstairs while we search."
"You"ve already searched her room."
"Not since Rawlins--"
Robinson caught himself.
"Never mind that. It is necessary it should be searched to-night. Even you"ll acknowledge it"s significant that all day when she has been downstairs her door has been locked."
"It"s only significant," Bobby flashed, "in view of your treatment of her yesterday."
Robinson grinned.
"That will hardly go down. Rawlins has hesitated to break in. I"ve instructed him to do it now, if necessary. For the last time, will you bring your cousin down? Will you go through and unlock the door leading from the old bedroom to the private hall so we can get up?"
"No," Bobby cried, "I wouldn"t do it if I believed you were right. And I know you"re wrong."
"Prove that we"re wrong. Clear your cousin by helping us," Robinson urged.
"Since you"re so determined," Graham said quietly, "I"ll do it."
"Hartley! What are you thinking of?"
"Of showing them how wrong they are," Graham said. "I"ll tell her Doctor Groom wishes to speak to her about Mr. Blackburn. I"ll warn him to keep her downstairs for a quarter of an hour. That should give you plenty of time."
Robinson nodded.
"She"ll never forgive you," Bobby said. "It"s spying."
He wondered that Graham should choose such a course so soon after it had become clear that Katherine had never really loved him.
"It"s the best way to satisfy them," Graham said. "I have, perhaps, more faith than you in Katherine."
He left them to carry out Robinson"s instructions. They waited at the entrance of the private staircase.
"I may witness this outrage?" Bobby asked.
"I"d rather you didn"t speak of it in such harsh terms," Robinson smiled.
Bobby didn"t know what to expect. The whole thing might be a trick of Paredes, in line with his hints the night of Howells"s death, to involve Katharine. The quiet confidence of the two officials was disturbing. What had Rawlins seen?
After a long time Graham descended the private staircase, carrying a lighted candle. He beckoned and they followed him back through the private hall into the wide and mournful bedroom. It encouraged Bobby to see the district attorney and the detective hurry across it. After all, they were really without confidence of solving its ghostly riddle. What they were about to do, he argued, was a last chance. They would find nothing. They would acknowledge themselves beaten.
When they entered the farther wing he noticed that Katherine"s door stood wide.
"You see," he said.
"When I called her," Graham explained, "she thought something had happened to her grandfather. She ran out."
"And forgot all about the door," Robinson grinned. "That"s lucky. Now, Rawlins."
Bobby couldn"t bring himself to cross the threshold, but from the corridor he could see the interior of the room and all that went on there during the next few moments. A candle burned on the bureau, exposing the feminine neatness and delicacy of the furnishings. The presence of the three men was a desecration; what they were about to do, an unforgivable act of vandalism.
Rawlins went to a work table while Robinson rummaged in the closet. Graham, meantime, bent against the footboard of the bed, watching with anxious eyes. Bobby"s anger was increased by this picture. He resisted an impulse to run to the stairs and call Katherine up. That would simply increase Robinson"s suspicions. There was nothing she could do, nothing he could do.
Rawlins had clearly been unsuccessful at the work table. He glided to the bureau. One after the other he opened the drawers, fumbling within, lifting the contents out, replacing them with a rough haste while Bobby"s futile rage increased.
Suddenly he saw Graham"s att.i.tude alter. Rawlins"s back stiffened. He pulled the bottom drawer altogether from the bureau and thrust it to one side. He gazed in the opening.
"Come here, Mr. Robinson," he said softly.
Robinson left the closet and stooped beside the detective. He exclaimed. Graham went closer looking over their backs.
"You"d better see, Bobby," he said without turning.
"Yes," Robinson said. "Let me show you how wrong you were, Mr. Blackburn. Let me ask if you knew you were wrong."
Bobby entered with a quicker pulse. He, too, stooped and looked in the opening. Abruptly everything altered for him. He wondered that his physical surroundings should remain the same, that the eager faces beside him should retain their familiar lines.
Against the back-board of the bureau, where it would fit neatly when the drawer was in place, lay a plaster cast of a footmark. Near by was a rumpled handkerchief that Bobby recognized as his own, and the envelope, containing Howells"s report which they had told Jenkins to hide.
"Well?" Robinson grinned.
"I swear I didn"t know they were there," Bobby answered. "You"ll never make me believe that Katherine knows it."
"I"ve guessed," Rawlins said, "that the stuff was hidden here ever since this afternoon when I saw a small bundle sneaked in."
"Who brought it?" Bobby took him up.
Robinson"s grin expanded.
"Leave us one or two surprises to spring in court."
"Then," Bobby said, "my cousin wasn"t in the room when this evidence was brought here."
"I"ll admit that," Rawlins answered, "but she wasn"t far away, and she got here before I could investigate, and she"s kept the door locked ever since until just now."
He lifted the exhibits out. The shape of the cast, the monogram on the handkerchief cried out their testimony.
Robinson grasped Howells"s report and glanced over the fine handwriting. After a time he looked up.
"There"s the case against you, Mr. Blackburn, and at the least your cousin"s an accessory. But why the devil did you come to me and make a clean breast of it?"
"Because," Bobby cried, "I didn"t know anything about these things being here. Can"t you see that?"
"That"s the trouble," Robinson answered uncertainly, "I think I do see it."
"Besides," Graham said, "you"re still without the instrument that caused death."
"I expect to land it in this room," Rawlins answered grimly.
He replaced the drawer and continued to fumble among the clothing it contained. All at once he called out and raised his hand. On the forefinger a tiny red stain showed.
"How did you do that?" Robinson asked.
"Something p.r.i.c.ked me," the detective answered. "Maybe it was only a pin, but it might have been--"
Excitedly he resumed his search. He took the clothing from the drawer and threw it to one side. Nothing remained in the drawer.
"I guess it must have been a pin," Robinson said, disappointed.
But Rawlins took up each article of clothing and examined it minutely. His face brightened.
"Here"s something stiff. By gad, I believe I"ve got it!"
Concealed in a woollen sack, with the slender shaft thrust through and through the folds, was a peculiarly long, stout, and sharp hat pin. Rawlins drew it out. He held it up triumphantly.
"Now maybe we"re not getting somewheres! That"s the boy that did the trick in both cases, and it"s what scratched Mr. Paredes. Maybe you noticed how quickly she came upstairs to hide this when she got in."
"Good work, Rawlins," Robinson said.
He glanced at Bobby and Graham.
"Have either of you seen this deadly thing before?"
Bobby wouldn"t answer, but after a moment"s hesitation Graham spoke: "There"s no point in lying, Bobby. Katherine knows nothing of this. I disagree with Rawlins. If she had been working with Paredes, which is unthinkable, she"d never have made such a mistake. She wouldn"t have struck him. I have seen her wear such a pin."
"If she didn"t cut him with it," Rawlins reasoned, "who else could have got it out of here and put it back to-night when she kept her door locked?"
