"Here, Conrad!" she called, going to the door.
A third party made his appearance on the scene, a boy who looked so much like Mrs.Hill that it was clear she was his mother.

He was two inches taller than Ben, but looked pale and flabby.
"What's wanted, ma ?" he said, staring at Ben.
"This young man has made a strange mistake.

He says Mrs.Hamilton has sent for him and that he is going to live here.
"He's got cheek," exclaimed Conrad, continuing to stare at Ben.
"Tell him he'd better go!" "You'd better go!" said the boy, like a parrot.
"Thank you," returned Ben, provoked, "but I mean to stay." "Go and call a policeman, Conrad," said Mrs.Hill.

"We'll see what he'll have to say then.".
