"What investigations?"
"In the field where the body was found first," West went on steadily, but no longer looking at her, "tracing the different tracks through the clover. Then I looked up that cottage in Arch Street, and thus learned about Hobart. Somehow he seemed to fit into the picture, and your mysterious visit there made me anxious to interview the man. He had left no address however, just faded out of sight suddenly, which increased suspicion. Then, when we were completely baffled, Sexton learned about your conversation over the telephone."
"How? Was he at the house?"
"Yes; he went out at my suggestion."
"And heard me repeat this number?"
"It makes no difference how he got the information; we knew you were coming here this afternoon, and jumped at the conclusion that you were going to meet Hobart for some reason."
"Very bright, I am sure," and there was a tone of relief in her voice. "And that is your whole story, I suppose? What does it amount to?"
"Not very much, perhaps."
"And the two of you came out here seeking to learn my business, to pry into my personal affairs. That was not a very gentlemanly act, Captain West, and I hardly see how you can justify yourself."
"I had two purposes," he insisted, "either of which justify. I felt it a duty to locate this man Hobart; and also to warn you of the danger you were in."
"Warn me!" she laughed scornfully. "That is ridiculous enough surely. I have a perfectly good reason for being here, but I am not accountable to you in any way for my movements. A duty you say--a duty to locate this man? A duty to whom?"
"To the State, if no one else," he answered gravely. "Percival Coolidge did not commit suicide; he was murdered."
"Murdered!" she came to her feet with utterance of the word. "You cannot think that!"
"I know it, Miss Natalie; the evidence is beyond question; he was murdered in cold blood."
"But by whom? for what purpose?"
"These points are not yet determined; I am only sure of the crime."
"Yes, but--but you suspect Jim Hobart. Isn't that true? You came here seeking him--yes, and me. You even think I know how this death occurred. You--you connect it with my fortune."
"No, Miss Natalie," he protested stoutly, moved by her agitation. "The cause is a mystery, and who did it equally mysterious. The evidence thus far unearthed is all circumstantial."
"Then why did you come out here searching for Hobart?"
"Because of his strange meeting with Percival Coolidge the very day of his death; because his sudden disappearance furnished the only clue."
