Horace wears a white lab coat with a teal shirt and tie underneath. He has blue hair and brown trousers.
When Professor Layton, Flora, Don Paolo and Luke went to investigate the Research Facility, they come across Horace. When Horace asks the team what they are doing there, the team gains his trust and Professor Layton promises to free Horace, Cuthbert and Avogadro from Dimitri Allen and allow them to travel back to present London.
Horace then guides the team through the Research Facility until they are stopped by Cuthbert. Horace then intervenes Cuthbert and explains that Professor Layton isn't the same Layton who controls the underworld.
Horace gives the following puzzles in Professor Layton and the Unwound Future:
"Horace is a scientist who was abducted and taken to Future London. He realized that the future Layton was in fact Dimitri but held his tongue following threats from the Family. He has a girlfriend down in Chinatown."
