Graham is a character appearing in Professor Layton and the Unwound Future. He could usually be found near the river Thames. Parrot stole his diamond cufflinks from him on one occasion, though he got it back with the help of both Luke and Future Luke. He claimed to be a true gentlemen, and said that if Luke kept up with what he was doing he too would be a true gentlemen. Graham also had an apparent business arrangement with Belle as well. Graham was found earlier on in the game on the way into Chinatown by the River Thames on the hill.
Graham gives Luke Triton and Future Luke a single puzzle "Cluttered Bag".
