Pembroke's family physician. I'm greatly surprised at this sudden death. I'm surprised, too, that Janet should faint away, for I have never known her to do such a thing before."

By this time we had all three crossed the hall, and were inside the Pembrokes' door, which opened into a short cross hall. On the right was the drawing-room, and here we found Miss Pembroke, who had not yet regained consciousness. She lay on a couch, and as the doctor bent over her she gave a convulsive shudder, but did not open her eyes.

"She'll be all right in a moment," said Doctor Masterson. "Janet is a plucky girl, and sound as a nut. I'll leave her in your care, Mrs. Mulford."

Laura was already hovering over the girl, and, with her intuitive womanliness, was doing exactly the right things.

The colored woman was crouched in a heap on the floor, and was rocking herself back and forth, with occasional wails.

"Stop that noise, Charlotte," commanded the doctor. "Don't make us any more trouble than we already have."

The command was not heeded, but without further comment he turned away from her, and as he beckoned to me I followed him from the room.

"I was at my wits' end," he exclaimed, "with those two women on my hands, and this dead man to look after!" As he spoke, we crossed the short hall and entered what was apparently the old gentleman's bedroom. I gazed with interest at the face of Robert Pembroke, and, save for what Doctor Masterson had told me, I should have thought I was looking at the face of a sleeping man. My first feeling was one of admiration, for the features were of classic mould, and the white hair, thick and rather long, waved back from a noble brow.

"What a handsome man!" I exclaimed involuntarily.

"Did you know him?" asked Doctor Masterson, looking at me keenly.

"No," I replied; "I've never seen him before. I've lived in this house but two weeks."

"Robert Pembroke was a handsome man," agreed the doctor, "but, with the best intentions, and with all the respect due the dead, there is little else good to be said of him. But his sudden death puzzles me greatly. I have been his physician for many years, and I should have said that he had not the least apoplectic tendency. Yet apoplexy must have caused his death—at least, so far as I can judge without a more thorough examination."

As he spoke Doctor Masterson was examining the body, and his look of bewilderment increased.

"He looks as if he were asleep," I said.

"That's just it," said the doctor. "There is no indication of a convulsive struggle or a spasm of any kind. His limbs are quietly composed, even relaxed, as if he had died in his sleep; which is not quite indicative of a stroke of apoplexy."

"Heart disease?" I suggested.

"He had no valvular trouble of the heart," said the doctor, who was continuing his examination. "He had gout, indigestion, rheumatism, and many ailments incidental to old age, but nothing organic, and I had supposed he would live many years longer to torment that poor girl in there."

"He was irascible, I know," I responded, feeling that I ought to say something.

"Irascible faintly expresses it," declared the Doctor, in a low voice; "he was cruel, domineering, tyrannical and of a brutal temper."

"And he vented it on innocent Miss Pembroke?"

"Yes; he did, though Janet is no patient Griselda. She can hold her own! I've known her to——"

Doctor Masterson ceased talking as he went on with his investigation.

A dozen questions rose to my lips, but I refrained from uttering them. Miss Pembroke's affairs were none of my business; and, too, the doctor was not definitely addressing me, but seemed rather to be talking to himself.

"Here's a key," he said, holding toward me a small bright key; "just take it for the moment, Mr. Landon, as it is doubtless an important one."

"Where was it?" I asked.

"On the bed, by Mr. Pembroke's side. It had probably been under his pillow. It looks like the key of a safety box of some sort."

I put the key in my pocket, with a pleased thought that it would give me an opportunity to speak with Miss Pembroke. Meantime I noticed that Doctor Masterson's attitude was becoming more and more that of a greatly perplexed man.

"I don't understand it," he muttered. "A man can't die without a cause. And every known cause shows its own symptom. But I find no symptoms. What can this man have died of?"

"No foul play, I hope," I observed.

"No, no; nothing of that sort! Mr. Pembroke died peacefully in his sleep. But how?"

Suddenly he straightened himself up with an air of resolve.

"Is there a doctor living in this house?" he asked.

"Yes," I answered; "there is one on the first floor. Shall I fetch him?"

"Do," said the old man. "Tell him that Doctor Masterson wishes to call him in consultation on a serious matter." I hastened on my errand, though not so rapidly as not to pause a moment to glance in at Miss Pembroke, who had recovered consciousness, and was lying quietly back on the sofa pillows, while Laura bathed her forehead with cologne. I well knew the soothing capabilities of Laura's finger-tips; and I also was not surprised to notice that the black girl had ceased her convulsive shuddering, and, though still sitting on the floor, was gazing at Laura as if fascinated.

All this I took in in a brief glance, and then ran hurriedly down the stairs in search of Doctor Post.

"Is this Doctor Post?" I asked as I entered his office.

"Yes," he replied, laying down the gloves and hat he held. Apparently, he was just about to go out, and I had fortunately arrived in time.

"Will you go up-stairs with me?" I went on. "Mr. Pembroke, on the third floor, is dead; and his physician, Doctor Masterson, is at a loss to discover the cause of his death. He sent me to ask you to join him in consultation."

"Doctor Masterson!" exclaimed Doctor Post, and I saw at once that the younger man was flattered at being called in consultation by the older and celebrated practitioner. "He wants me?" he asked, as if scarcely able to believe it.

"Yes; it is a peculiar case, and he asks your help. Will you go with me at once?"

"Certainly," and in another moment Doctor Post and I were in the elevator.

"Old Mr. Pembroke dead?" asked the boy as we entered.

"Yes," I answered briefly.

"Gee, is he? Well, I can't give him any weeps! He was sumpin fierce! He just put it all over that young loidy. Sometimes she'd come down in this elevator all to the teary, so's I 'most hadta order a consignment of weep-catchers for myself. She's a looker all right, and she sets off the house great, but she leads the dismal swamp life, an' that's right!"

I had neither time nor inclination then to reprove the boy for thus crudely expressing his opinion, for we had reached the third floor, and Doctor Post and I went at once to Robert Pembroke's bedroom.

I introduced the new-comer to his older colleague, and then turned aside while they consulted on the problem that faced them.

I was surprised that a physician of Doctor Masterson's age and experience should find it necessary to call the younger man to his aid, but as I knew little of medical men and their ways, I had no definite opinion on the subject. I felt a slight embarrassment as to my own presence in the room, but I also felt a hesitancy about returning to the drawing-room until the doctors should have reached a decision. I endeavored not to hear the low words they were speaking, but I couldn't help gathering
