DLC Mehrunes' Razor
Keep searching for the writ that assassin carries. The patrolmen have searched the tunnels in hopes that he dumped it when he was found out, but he may carry it on his person yet. If that's the case, I shudder to think where it's hidden. Try sneaking in there while he's sleeping to search the cell.
And by Nerevar, get to work building that second cell! I don't want to execute that assassin until we find out who he came for, and Sardova needs someplace to lock up the workers when they get out of line.
