“Do you think that if there had been any tick-tack then you would have heard it, with all those persons talking in the room?”

“I hear everything. I hear everything.”

“Did you go downstairs at the same time those people did?”

“No, no; I remained near the general for some time, until he was sound asleep.”

“And you heard nothing?”

“Nothing.”

“You closed the doors behind those persons?”

“Yes, the door to the great staircase. The door of the servants’ stairway was condemned a long time ago; it has been locked by me, I alone have the key and on the inside of the door opening into the general’s chamber there is also a bolt which is always shot. All the other doors of the chambers have been condemned by me. In order to enter any of the four rooms on this floor it is necessary now to pass by the door of my chamber, which gives on the main staircase.”

“Perfect. Then, no one has been able to enter the apartment. No one had been in the apartment for at least two hours excepting you and the general, when you heard the clockwork. From that the only conclusion is that only the general and you could have started it going.”

“What are you trying to say?” Matrena demanded, astounded.
