A letter written by Simon Barnaky to his wife, Maria Barnaky. It is found on Toccomatta's corpse during the Osceolla mission. If kept until the end of the game, it could be used to persuade the renegade general Barnaky to stop supporting Calculator.
An item named General's locket serves the same purpose as the letter. The only difference is that the dialog it triggers is slightly different.
