Pratchett's safe in his house near Kaldwin's Bridge. The combination is given by Bunting when interrogating him at the Golden Cat, provided that Corvo has first either visited the safe or Slackjaw has given Corvo a second mission. It can also be recovered from an Overseer named Overseer Berthold, if Corvo chooses to save him and his sister, Elsa, from his fellow Overseers. The combination can be found in three different locations: in the alley past Holger Square in a note in the mess hall and under the bed to the left of the safe. The barracks safe in the Overseer's Back Yard. The clue is in the kennel cell with the two prisoner corpses. The locked kennel door in the kennel below the Office of the High Overseer. The code is also written on the corner of one of his chalkboards displaying a drawing of a whale. The clue is in Doctor Galvani's building reading his journal hints that his favorite numbers are the combination. The combination is found by looking past the empty bottles on the shelf behind the safe. A note written for a man named Jelly can be found nearby.

The safe in the sewers past the spot where Corvo Attano gets his gear.
