A theme in Vestry of Monnow is the relationship between obedience and sanity. The actual nut house was called The Tri County Lunatic Asylum or Pen-y-Fal. A wonderfully scary Victorian structure with beautiful gardens, there was even a heated green house and vegetable growing.
The thing about this particular Tri County Lunatic Asylum is that recently,
maybe twenty or thirty years ago, it was converted into very expensive
apartments. Back in the day of course our hero had to qualify to get into
Pen-y-Fal. And he can assure you the examination was great deal harder than his
Geography A Level.
