"How came you to know that?" inquired the elder servant, sharply.
"Hush!" cried the other, rising quickly from his chair.
A bell rang in the passage outside.
"Is that for one of us?" asked Mathew.
"Can't you tell, by the sound, which is which of those bells yet?" exclaimed Robert, contemptuously. "That bell is for Sarah Leeson. Go out into the passage and look."
The younger servant took a candle and obeyed. When he opened the kitchen-door, a long row of bells met his eye on the wall opposite. Above each of them was painted, in neat black letters, the distinguishing title of the servant whom it was specially intended to summon. The row of letters began with Housekeeper and Butler, and ended with Kitchen-maid and Footman's Boy.
Looking along the bells, Mathew easily discovered that one of them was still in motion. Above it were the words Lady's-Maid. Observing this, he passed quickly along the passage, and knocked at an old-fashioned oak door at the end of it. No answer being given, he opened the door and looked into the room. It was dark and empty.
"Sarah is not in the housekeeper's room," said Mathew, returning to his fellow-servant in the kitchen.
"She is gone to her own room, then," rejoined the other. "Go up and tell her that she is wanted by her mistress."
The bell rang again as Mathew went out.
