situation that the two doctors came. They looked exceedingly grave; indeed, their faces bore an expression of awe that seemed even beyond what the case demanded.

"Ah, George," said Doctor Masterson, grasping the hand of the young man, "I'm glad you're here. Did Janet send for you?"

"Yes, doctor; she telephoned, and I came at once. I'm indeed surprised and shocked at Uncle Robert's sudden death. Had you ever thought such a thing likely to happen?"

"No," said Doctor Masterson, and his voice had a peculiar ring, as of a man proving his own opinion.

Apparently Janet Pembroke was accustomed to the inflections of the old doctor's voice, for she looked suddenly up at him, as if he had said something more. Her crying spell was over, for the time at least, and her white face had again assumed its haughty and inscrutable expression.

"Was it heart disease?" she inquired, looking straight at Doctor Masterson.

"No," he replied; "it was not. Nor was it apoplexy, nor disease of any sort. Mr. Robert Pembroke did not die a natural death; he was killed while he slept."

I suppose to a man of Doctor Masterson's brusk, curt manner it was natural to announce this fact so baldly; but it seemed to me nothing short of brutality to fling the statement in the face of that quivering, shrinking girl.

"Killed!" she said, clasping her hands tightly. "Murdered!"

"Yes," said the doctor; "murdered in a peculiar fashion, and by a means of devilish ingenuity. Indeed, I must confess that had it not been for Doctor Post's conviction that the death was not natural, and his determination to discover the cause, it might never have been found out."

"Was he shot?" asked Janet, and it seemed to me she spoke like one in a trance.

"Shot? No!" said Doctor Masterson. "He was stabbed, or rather pierced, with a long, thin pin—a hat-pin, you know. Stabbed in the back of his neck, at the base of the brain, as he lay asleep. He never knew it. The pin broke off in the wound, and death was immediate, caused by cerebral hemorrhage. Doctor Post and I have made a most thorough examination, and we are convinced that these are the facts. Mr. Pembroke was lying on his side, in a most natural position, and was, in all probability, sleeping soundly. This gave the murderer an excellent opportunity to aim the deadly pin with careful precision, and to pierce the brain with a swift stab. The result of this was precisely the same as a sudden and fatal apoplectic stroke. Though there may have been a tremor or slight quiver of certain muscles, there was no convulsion or contortion, and Mr. Pembroke's face still retains the placid look of sleep. Death must have taken place, we conclude, at or near midnight."

We who heard this sat as if paralyzed. It was so unexpected, so fearfully sudden, so appalling, that there seemed to be no words fit to express our feelings.

Then George Lawrence spoke. "Who did it?" he said, and his white face and compressed lips showed the struggle he was making for self-control.

"I don't know," and Doctor Masterson spoke mechanically, as if thinking of something else.

"No, of course, we don't know," broke in Doctor Post, who seemed a bit inclined to emphasize his own importance. And perhaps this was but natural, as the older doctor had plainly stated that but for Doctor Post's insistent investigation they might never have discovered the crime.

"But we must immediately set to work to find out who did this dreadful deed," Doctor Post went on; and though I felt repelled at the avidity he showed, I knew he was right. Though the others seemed partially stunned by the suddenly disclosed fact, I foresaw the dreadful experiences that must follow in its train.

Miss Pembroke, though still sitting by Laura's side, had broken away from her encircling arm. The girl sat upright, her great eyes fixed on Doctor Masterson's face. She showed no visible emotion, but seemed to be striving to realize the situation.

"Murdered!" she breathed in a low whisper; "Uncle Robert murdered!"

Then, without another word, her eyes traveled slowly round the room, resting on each person in turn. Her glance was calm, yet questioning. It almost seemed as if she suspected some one of us to be guilty of the crime. Or was it that she was seeking help and sympathy for herself? If so she could stop with me. She need look no further. I knew that in the near future she would want help, and that of a legal nature. She had herself said, or at least implied, that she would not look for such help from Graham Leroy. If this were true, and not merely a bit of feminine perversity, I vowed to myself that mine should be the helping hand outstretched to her in her hour of need.

"There is much to be done," Doctor Post continued, and his mind was so occupied with the greater facts of the situation, that he almost ignored Miss Pembroke. He addressed himself to Doctor Masterson, but it was easily seen that this was a mere form, and he himself quite evidently intended to be the real director of affairs. "We must find out who was the intruder, doubtless a professional burglar, who committed this awful deed. We must search the room for clues, and that, too, at once, before time and circumstance may obliterate them."

Although I didn't show it, I couldn't help a slight feeling of amusement at this speech. It was so palpably evident that Doctor Post possessed what he himself would doubtless call the Detective Instinct; and, moreover, it was clearly indicated that his knowledge of the proper methods of procedure were gained from the best detective fiction! Not that he was wrong in his suggestion, but it was not the time, nor was it his place to investigate the hypothetical "clues."

Doctor Masterson appreciated this point, and with a slightly disapproving shake of his wise, old head, he observed: "I think those things are not in our province, Doctor Post. We have performed our duty. We have learned the method and means of Robert Pembroke's death; we have made our report, and our duties are ended. The case has passed out of our hands, and such details as clues and evidence, are in the domain of the coroner and inspector."

Doctor Post looked a little chagrined. But he quickly covered it, and effusively agreed with the older doctor.

"Quite so, quite so," he said; "I was merely suggesting, in what is perhaps an over-zealous desire to be of assistance. What you say, Doctor Masterson, is entirely true. And now," he added, again bristling with an assumption of importance, "and now, we must send for the coroner."
