“I fear she is dying,” whispered Monsieur Gustave.

“No, no, surely not!” cried Captain Fennel, recoiling a step at the words. “What can it possibly be? What causes the attacks?”

Whilst Monsieur Gustave was shaking his head at this difficult question, Monsieur Dupuis arrived. Monsieur Emile, anxious to make himself useful, was requested by Mariette to go to Flore’s domicile and ring her up. Flore seemed to have been sleeping with her clothes on, for they came back together.

Monsieur Dupuis could do nothing for his patient. He strove to administer drops of medicinal remedies; he caused her to be nearly smothered in scalding-hot flannels—all in vain. He despatched Monsieur Emile Sauvage to bring in another doctor, Monsieur Podevin, who lived near. All in vain. Lavinia died. Just at one o’clock in the morning, before the cocks had begun to crow, Lavinia Preen died.

The shock to those in the house was great. It seemed to stun them, one and all. The brothers Sauvage, leaving a few words of heartfelt sympathy with Captain Fennel, withdrew silently to their own home. Mariette stayed. The two doctors, shut up in the salon, talked with one another, endeavouring to account for the death.

“Inflammation, no doubt,” observed Monsieur Dupuis; “but even so, the death has been too speedy.”

“More like poison,” rejoined the younger man, Monsieur Podevin. He was brother to the proprietor of the Hôtel des Princes, and was much respected by his fellow-citizens as a safe and skilful practitioner.

“The thought of poison naturally occurred to me on Sunday, when I was first called to her,” returned Monsieur Dupuis, “but it could not be borne out. You see, she had partaken of nothing, either in food or drink, but what the other inmates had taken; absolutely nothing. This was assured me by them all, herself included.”

“She seems to have taken nothing to-day, either, that could in any way harm her,” said Monsieur Podevin.

“Nothing. She took a cup of tea at five o’clock, which the servant, Flore, prepared and also partook of herself—a cup out of the same teapot. Later, when the poor lady went to bed, her sister made her a basin of arrowroot, and made herself one at the same time.”
