Light o' the Morning by L.T. Meade

It was between two and three in the morning when the girls found themselves back again in the desolate mansion of Cronane. Biddy had left a window open; they had easily got in by it and gone up to Biddy's big room on the first floor. They were to sleep together in Biddy's small bed. Personally, discomforts did not affect them; they had never been accustomed to luxury, and rather liked the sense of hardship than otherwise.

"I brought up a bit of supper beforehand," said Biddy. "I am real hungry. What do you say to cold bacon and taters -- eh? I went down to the larder and got a good few early this morning. I put them in the cupboard in a brown bowl with a plate over it. You're hungry -- aren't you, Norrie?"
