I looked at Laura with admiring affection, for I saw at once that she had realized that Miss Pembroke was in serious trouble of some sort, and her true womanly heart went out to the girl, forgetting entirely her previous dislike and suspicion.

Almost immediately our door-bell rang, and, feeling sure that it was a summons in response to my offer, I opened the door myself.

Sure enough, there stood the elderly doctor, looking very much perturbed.

"You kindly offered your assistance, sir," he said, "or I should not intrude. I want immediate help. Mr. Pembroke is dead, Miss Pembroke has fainted, and their servant is so nearly in hysterics that she is of no use whatever."

Laura is always splendid in an emergency, so of course she rose to the occasion at once.

"Let me go to Miss Pembroke," she said, in her quiet, capable way. "I'm Mrs. Mulford, and this is my brother, Otis Landon. We are new-comers here, and do not know Miss Pembroke personally, but we are only too glad to do anything we can for her."

"Thank you," said the old gentleman, looking at Laura with an air of approval. "I'm Doctor Masterson, the 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.
