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 assuredly 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 mass 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?"
