My left side functionality is still impaired but improving with physiotherapy. 

While my back was turned, though, I discover the Inspector who was trying to exercise some small level of control over the PCs has just been "reassigned", so can no longer help, and his replacement is on leave, because of course he is. 

Obviously, It's way too much to hope for any sort of continuity so I will have to go through the whole painful process again from strach with the new guy.
