“Doctor,” she said, coldly and mechanically, as if she was repeating a lesson, “I am as curious as the other ladies about that pretty cabinet of yours. Now they are all gone, won’t you show the inside of it to me?”

The doctor laughed in his pleasantest manner.

“The old story,” he said. “Blue-Beard’s locked chamber, and female curiosity! (Don’t go, Benjamin, don’t go.) My dear lady, what interest can you possibly have in looking at a medical bottle, simply because it happens to be a bottle of poison?”

She repeated her lesson for the second time.

“I have the interest of looking at it,” she said, “and of thinking, if it got into some people’s hands, of the terrible things it might do.”

The doctor glanced at his assistant with a compassionate smile.

“Curious, Benjamin,” he said, “the romantic view taken of these drugs of ours by the unscientific mind! My dear lady,” he added, turning to Miss Gwilt, “if that is the interest you attach to looking at poisons, you needn’t ask me to unlock my cabinet—you need only look about you round the shelves of this room. There are all sorts of medical liquids and substances in those bottles—most innocent, most useful in themselves—which, in combination with other substances and other liquids, become poisons as terrible and as deadly as any that I have in my cabinet under lock and key.”

She looked at him for a moment, and creased to the opposite side of the room.

“Show me one,” she said,

Still smiling as good-humoredly as ever, the doctor humored his nervous patient. He pointed to the bottle from which he had privately removed the yellow liquid on the previous day, and which he had filled up again with a carefully-colored imitation in the shape of a mixture of his own.
