“Yes, the head of the household has been called away for a day or two, and there is no man in the house. Mrs. Cunningham is timid, and has sent for a boy to protect the house against possible burglars.”
The superintendent smiled, and so did Paul.
“I guess I can do it,” he said.
“Very well, you will report at the house about seven o’clock.”
“Can I go home and tell grandfather? He might be alarmed if I didn’t come home.”
“Yes; I will give you an extra half hour for supper.”
At seven o’clock Paul rang the bell of a handsome brown stone mansion on West Fifty First Street.
The door was opened by a servant girl.
