Jr. Horatio Alger 
Store Boy 

Another in the popular series of tales about real boys who 'did honest things successfully’. Several years have elapsed. Ben is in the office of a real estate lawyer in New York, as junior partner. All Mrs. Hamilton’s business is in his hands, and it is generally thought that he will receive a handsome legacy from her eventually. Mrs. Barclay prefers to live in Pentonville, but Ben often visits her. Whenever he goes to Pentonville he never fails to call on Rose Gardiner, now a beautiful young lady of marriageable age. She has lost none of her partiality for Ben, and it is generally understood that they are engaged. (Goodreads)
