He now started from his seat, and looking round him, perceived the Closet door standing half-unclosed.

On his first entering the room He had tried to open it, but found it bolted on the inside.
'How is this ?' said He to himself; 'How comes this door unfastened ?' He advanced towards it: He pushed it open, and looked into the closet: No one was there.

While He stood irresolute, He thought that He distinguished a groaning in the adjacent chamber: It was Antonia's, and He supposed that the drops began to take effect: But upon listening more attentively, He found the noise to be caused by Jacintha, who had fallen asleep by the Lady's Bedside, and was snoring most lustily.

Ambrosio drew back, and returned to the other room, musing upon the sudden opening of the Closet door, for which He strove in vain to account.
He paced the chamber up and down in silence.

At length He stopped, and the Bed attracted his attention.
