"Mother Watson's nephew," said Ben, with a grimace.

"He's only joking, sir," said Mark. "My name is Mark Manton."

"I am glad to see you, Mark," said the superintendent. "What is your business?"

"I sell matches, sir."

"Have you parents living?"

"No, sir; they are both dead."

"Where have you been living?"

"In Vandewater Street."

"With any one?"

"Yes, with a woman they call Mother Watson."
