This is the second book in the Elfie and Joe trilogy.
When Elfie's best friend, Joe, starts work as a clerk in her father's office, Elfie is delighted. Unfortunately, Joe's not the only new person working in the lawyer's office in Chancery Lane. Mr Trelawney's bigoted partner Mr Basildon-Blunt takes an instant dislike to Joe and worse, he seems to have some hold over Elfie's father.
