Much Ado About Peter [EPUB ebook] 

We follow Peter’s life while working as a groom for the wealthy Carter family. He has to deal with rowdy young children of his upper class employers, who tend to both look down and up to Peter. There’s plenty of slapstick humor with pranks and tricks being played by the children. Later, Peter starts making odd and questionable decisions, but all ends up well. (Goodreads)
