Converse, however, was far from faltering before this stern, not to say menacing, attitude; his own huge frame was the embodiment of resolution, the cold light of his eye the reflection of an inflexible, constraining personality, intent with a fixed determination; and the look with which he met Dr. Westbrook's infuriated glance did more to calm the latter than any speech could have done. The Doctor all at once sat down again, signifying by a slight gesture that the other might proceed.

"Doctor," the Captain went on immediately, "you will do well if you try to curb your impatience, for at the very best what I have to say to you will not be pleasant. Perhaps you will see it in the light of necessity when I tell you I have taken pains to secure this conference against interruption." And he concluded, grimly, "It is necessary—or something worse."

"Well, what is it?" was the response, uttered with a touch of testiness. "I hope the result will justify your assurance. I'm in no humor to trifle."

"And you will find it no trifling matter." The speaker paused; concluding with a deliberateness of manner that made the words vastly portentous: "Doctor Westbrook, if the Coroner and the District Attorney had in their possession the facts—not theories, mind, but facts which can now be proved,—if they had laid before them all that I know, they would order your sister placed under immediate arrest."

If the Captain's intention was to impress the gravity of the situation upon the physician, he must have been eminently satisfied. Doctor Westbrook collapsed as if he had received a powerful physical blow; his face was haggard already, and now his eyes became fixed upon his interlocutor, intent, fascinated.

"So, you see, Doctor," Converse went on, "I am going outside my duty in giving you this opportunity to clear up some particulars, which it has been in your power to do since—well, I will fix the time by the death of De Sanchez."

After a silence which seemed to grow interminable, Doctor Westbrook cleared his throat, and hoarsely asked: "What do you wish? Dispense with preliminaries; what do you want of me?"

"Very good. I want you to summon Miss Westbrook here, and in your presence I shall put to her a number of questions. Of course she may answer them or not as she sees fit; but you must understand now and clearly, Doctor, that whatever the next immediate action taken by me may be, it will depend largely upon the outcome of this interview. If I am inconsiderate in any particular, pray say so, and I shall try to accommodate myself to your own and your sister's feelings in the matter. Now go; consult Miss Westbrook's wishes, but please be expeditious. Meet me here"—with a glance at his watch—"say, in thirty minutes." And without another word or a look back he quitted the room.

In the hall he encountered Sam, who, since the tragedy, seemed to have no more weighty occupation than to wander aimlessly about in a feeble effort to adjust himself to a novel and incomprehensible condition. His face lighted at sight of the Captain.

"Sam," said Mr. Converse, "I should like to have a look at that ash-hopper now."
