Meeting with Samuel | Mission 2 - High Overseer Campbell Dishonored Guide
Last update: 11 May 2016
You need to go and meet with Samuel regardless of whether you have explored and secured the yard or not. In the latter case, you should be careful and move around on building roofs to the extent it is possible. You need to reach the building closest to the cliff (the above screenshot).
Go through the abovementioned building and turn left. Stop in the spot shown in the above screenshot and use the chain to reach lower level.
Look around for gold and approach Samuel to initiate a conversation. Confirm that you indeed want to leave the area (the upper-right dialogue option) and return to the pub.
