Dupree hides behind a newspaper most of the time and wears a orange sweater, purple trousers and a lighter orange shirt underneath.
When Professor Layton and Luke first travel to Future London, they come across a man who is reading a newspaper, that is 10 years in the future. This man is Dupree, who confirms to the duo that they are actually in the future. Dupree continues to explain about The Family taking over from the police in Future London.
Later on in the game when Inspector Chelmey and Barton travel to Future London with Flora, Luke and Professor Layton, Dupree and Inspector Chelmey are found quarrelling when Dupree says that the police have no power in Future London, which offended Chelmey.
Dupree gives the following puzzles in Professor Layton and the Unwound Future:
"Dupree is the bearded man who spends his time reading the newspaper. He has a great love of justice and despises all that is evil, but his tendency to believe everything he reads in the newspaper without question has made him the Family's puppet."
