“Perfectly, my dear child. I need not approach the topics on which she desires our silence. Now, the marvel of last night consists in your having been removed from your bed and your room, without being wakened, and this removal having occurred apparently while the windows were still secured, and the two doors locked upon the inside. I will tell you my theory and ask you a question.”
Carmilla was leaning on her hand dejectedly; Madame and I were listening breathlessly.
“Now, my question is this. Have you ever been suspected of walking in your sleep?”
“Never, since I was very young indeed.”
“But you did walk in your sleep when you were young?”
“Yes; I know I did. I have been told so often by my old nurse.”
My father smiled and nodded.
“Well, what has happened is this. You got up in your sleep, unlocked the door, not leaving the key, as usual, in the lock, but taking it out and locking it on the outside; you again took the key out, and carried it away with you to some one of the five-and-twenty rooms on this floor, or perhaps upstairs or downstairs. There are so many rooms and closets, so much heavy furniture, and such accumulations of lumber, that it would require a week to search this old house thoroughly. Do you see, now, what I mean?”
“I do, but not all,” she answered.
“And how, papa, do you account for her finding herself on the sofa in the dressing room, which we had searched so carefully?”
