Lewton: The star of Discworld Noir, Lewton is the Discworld's first PI, and former watchman who left the watch in mysterious circumstances who he finds himself in a whole lot of trouble when a broad walks into his office and gives him a case that turns out to be more complicated than it looks.

Carlotta Von Uberwald: Carlotta is the aforementioned femme fatale, who walks into Lewton's office and gives him what appears to be a straightforward case. However, as the game progresses, it becomes clear that, in true film noir style, she has ulterior motives.

Al Khali: This character is Horsts dwarven associate, a sneaky, devious creature who isn't exactly trustworthy.

Horst: A troll with a granite finger in a great many pies, Horst, on another world, would probably be played Sidney Greenstreet, and can prove to be a useful source of information and illicit goods, although whether his information is on the level is something Lewton will have to work out for himself.

Ilsa: Ilsa is Lewton's old flame, currently engaged to an Agatean Archaeologist, but whom Lewton still holds a torch for. But does she still harbour any feels for Lewton? Only time will tell.

Two Conkers: The Agatean Archaeologist to whom Ilsa, Lewton's former flame, is engaged, Two Conkers spends a lot of time poking around in trenches looking for artifacts, though he's more Tony Robinson than Indiana Jones. He also bears a passing resemblance to a certain Agatean tourist whom Discworld fans may be familiar with.

Leonard Da Quirm: An inventor with a gift for coming up with strange, complicated and sometimes dangerous inventions, although not to good at naming them, Leonard currently lives in a cell at the Patrician's palace, hopefully out of harms way, although with a genius like Leonard, you can never be totally sure.
