"Mr. Mansell," the District Attorney now observed, "we have no motive in deceiving or even in misleading you. You were in this town on the morning of your aunt's murder, and you were even in her house. Evidence which you cannot dispute proves this, and the question that now arises, and of whose importance we leave you to judge, is whether you were there prior to the visit of Mr. Hildreth, or after. Any proof you may have to show that it was before will receive its due consideration." A change, decided as it was involuntary, took place in the hitherto undisturbed countenance of Craik Mansell. Leaning forward, he surveyed Mr. Ferris with great earnestness. "I asked that man," said he, pointing with a steady forefinger at the somewhat abashed detective, "if I were not wanted here simply as a witness, and he did not say No. Now, sir," he continued, turning back with a slight gesture of disdain to the District Attorney, "was the man right in allowing me to believe such a fact, or was he not? I would like an answer to my question before I proceed further, if you please." "You shall have it, Mr. Mansell. If this man did not answer you, it was probably because he did not feel justified in so doing. He knew I had summoned you here in the hope of receiving such explanations of your late conduct as should satisfy me you had nothing to do with your aunt's murder. The claims upon my consideration, which are held by certain persons allied to you in this matter"--Mr. Ferris' look was eloquent of his real meaning here--"are my sole justification for this somewhat unusual method of dealing with a suspected man." A smile, bitter, oh, how bitter in its irony! traversed the firm-set lips of Craik Mansell for a moment, then he bowed with a show of deference to the District Attorney, and settling into the attitude of a man willing to plead his own cause, responded: "It would be more just, perhaps, if I first heard the reasons you have for suspecting me, before I attempt to advance arguments to prove the injustice of your suspicions." "Well," said Mr. Ferris, "you shall have them. If frankness on my part can do aught to avert the terrible scandal which your arrest and its consequent developments would cause, I am willing to sacrifice thus much to my friendship for Mr. Orcutt. But if I do this, I shall expect an equal frankness in return. The matter is too serious for subterfuge." The other merely waved his hand. "The reasons," proceeded Mr. Ferris, "for considering you a party as much open to suspicion as Mr. Hildreth, are several. First, we have evidence to prove your great desire for a sum of money equal to your aunt's savings, in order to introduce an invention which you have just patented.
