This quest can be acquired from Matthew or Fritz, Henry's friends from Skalitz, who can now be found at the lodgings south of the monastery.
Speak with either Matthew or Fritz to reconcile with old friends. They will inform you that they are now jobless, and that they are having trouble finding work in Sasau. Agree to help them find work and begin by visiting Theresa at Rattay Mill. Ask Theresa if there is any work available at her uncle Peshek's mill.
Although Theresa will inform you that there is no work for two carpenters in all of Rattay, she refers you to the miller in Ledetchko, who is now rather old and could probably make use of two young workers. Speak with Miller Oliver at Ledetchko about the possibility of him employing Matthew and Fritz. You will have to use some form of persuasion to ensure that he trusts the word that you put in for them.
Return to Matthew and Fritz to inform them that there is work to be had in Ledetchko. They will not be able to repay you yet, but remember to visit them in a week to see how they are doing.
