You're not certain that the water in this bottle is poisoned?"
"No … it's possible"
"Still, just now"
"I thought so. But no … no!"
"It's easy to make sure," said Perenna, putting out his hand for the water bottle.
She was quicker than he, seized it and, with one blow, broke it against the table.
"What are you doing?" he said angrily.
"I made a mistake. And so there is no need to attach any importance"
Don Luis hurriedly left the dining-room. By his orders, the water which he drank was drawn from a filter that stood in a pantry at the end of the passage leading from the dining-room to the kitchens and beyond. He ran to it and took from a shelf a bowl which he filled with water from the filter. Then, continuing to follow the passage, which at this spot branched off toward the yard, he called Mirza, the puppy, who was playing by the stables.
"Here," he said, putting the bowl in front of her.
The puppy began to drink. But she stopped almost at once and stood motionless, with her paws tense and stiff. A shiver passed through the little body. The dog gave a hoarse groan, spun round two or three times, and fell.
"She's dead," he said, after touching the animal.
Mlle. Levasseur had joined him. He turned to her and rapped out:
"You were right about the poison—and you knew it. How did you know it?"
