Firth is a farmer from Craggy Dale that made a minor appearance in the game Professor Layton and the Miracle Mask. Before he was a farmer, he was an explorer. This hobby matched the hobby of his employee, Randall Ascot.
Firth wears a red coat over a yellow shirt, and green pants. He also wears brown shoes and a green hat, and has overgrown grey hair and a beard that hides his face.
Firth gives you the following puzzles throughout the game Professor Layton and the Miracle Mask:
Chapter 5: Miracles Unmasked
Professor Layton and the group meet Firth on Knickknack Alley, who was in need of help as he couldn't find his way around Monte d'Or. He was having trouble reading his map, and so Layton assists him. His ability to solve puzzles is highly noted, and Firth wonders how he would go against his friend who was mad about puzzles himself. Firth tells Layton he had come to Monte d'Or to look for this friend of his, who he treated like his own son. He had run off a few months prior, and so came to Monte d'Or in the hopes of finding him.
In a special episode, Firth meets Esther, who told him he was in the wrong quarter if he was looking for the sights of Monte d'Or. He tells her he was in Monte d'Or to find a friend he had been taking care of for 18 years, but had suddenly left for Monte d'Or two months prior. He came to the city in the hopes of finding him, and tells Esther he was from Craggy Dale. The two introduce themselves, and Esther invites Firth around for tea and pastries.
Firth is found again at Pumpkin Park, where he found the lights to be too bright, and was sweating inside his own beard. He had wanted to trim it, but couldn't find a decent barber in town. He then wonders if the Masked Gentleman was still making his appearances, as he couldn't tell from all the rumors.
Chapter 7: The Reunion Inn
Firth remembers that when he was young, Monte d'Or was only just sand, and lots of it. He says that to travel through the desert, they had to find a water source, which was now Monte d'Or. He also states that Craggy Dale and the oasis shared the same water source, and confirms it is all connected through an underground source.
"You wouldn't expect it, but beneath placid Mr. Firth's reams of hair lies a rather stern and frightening face. He spends most of his days leading a peaceful, ascetic life in the village of Craggy Dale. But if he decided to one day take on Lady Luck, he'd do so with bags of money."
