A very Naughty Girl by L.T. Meade

Anger gave Mr. Leeson a false strength. He put the canvas bags of gold into a large cupboard in the parlor; he locked the door and put the key into his pocket. Then he went gingerly and on tiptoe to another cupboard, and took down out of the midst of an array of dirty empty bottles one which contained a very little brandy. He kept this brandy here so that no one should guess at its existence. He poured himself out about a thimbleful of the potent spirit and drank it off. He then returned the bottle to its place, and fumbling in a lower shelf, collected some implements together. With these he went out into the open air.

He now approached the window where the light shone -- the faint, dim light which flickered against the blind and seemed almost to go out, and then shone once more. Slowly and dexterously he cut, with a diamond which he had brought for the purpose, a square of glass out of the lower pane. He put the glass on the ground, and slipping in his hand, pushed back the bolt. All his movements were quiet. He said "Ah! " once or twice under his breath. When he had gently and very softly lifted the sash, he took a handkerchief from his pocket and wiped away some drops which stood on his forehead. Then he said "Ah! " once more, and slipped softly, deftly, and quietly into the room. He had made no noise whatsoever. The young sleepers never moved. He stood in the fire-lit, and in his opinion lavishly furnished, room. Here was a small white bed and an occupant; here a larger bed and another occupant. He crept on tiptoe towards the two beds. He bent down over the little occupant of the smaller bed.
