George Arlington is a rich Hogson collector from the United States and appears in the episode The Black Book. Due to his considerable wealth and his obsession with Hogson, the price of Hogson's paintings has risen astronomically. Arlington first appears at the auction of Bishop's Drift, and successfully bids for the painting. Later on, he is blackmailed by Anthony Prideaux, who has proof that half of Arlington's collection are forgeries. After Prideaux is murdered, Barnaby convinces Arlington to take part in a sting that will catch the murderer. After the killer has been apprehended, Arlington double crosses Barnaby and Jones and takes the Black Book, the proof Prideaux had to repudiate Arlington's collection. With Matilda Simms, Arlington destroys the Black Book and any remaining fake Hogsons, "thus bringing an end to this unhappy chapter".
