Adelaida had long since detected in Aglaya’s features the gathering signs of an approaching storm of laughter, which she restrained with amazing self-control.

Aglaya looked menacingly at her laughing sisters, but could not contain herself any longer, and the next minute she too had burst into an irrepressible, and almost hysterical, fit of mirth. At length she jumped up, and ran out of the room.

“I knew it was all a joke!” cried Adelaida. “I felt it ever since⁠—since the hedgehog.”

“No, no! I cannot allow this⁠—this is a little too much,” cried Lizabetha Prokofievna, exploding with rage, and she rose from her seat and followed Aglaya out of the room as quickly as she could.

The two sisters hurriedly went after her.
