Biography
Derrick was born on an unknown date, to Lysander and Edith Green. Derrick's mother was killed in a boating accident when Derrick was 9, something which affected him largely until his new nanny, Sarah Piggins, arrived, which began to make life easier for him. He and his two siblings, Samantha and Michael, immediately began to have easier lives and enjoy themselves more. However, Mr Green has several times tried to get rid of Nanny Piggins, having low self-esteem about having a pig for a nanny. These several attempts were all successfully marred, much to Mr Green's disappointment.

Derrick, Samantha, Michael, Sarah and Boris stop Nanny Piggins from being sacked in book 2, and Mr Green's "poo-brown" Rolls Royce is driven away by Sarah's sister Charlotte, who marries men for their cars and poses as a beautiful and ordinary woman.
