I've always found the Merrrily Watkins stories cleverly  avoid coming down on either side of the fence in the demonic evil versus  mental health issues debate.  This book seems even more enigmatic, are the issues the result of an evil person and haunting historic events or is it all a big coincidence.
  The way such conflict is managed by the church is a big part of the story. It is set in the run up to and early part of the Covid lockdown it  also combines Wordsworth's love for the Wye Valley and his mystical experience when meeting a little girl there.
Will Merrily keep her job both as a priest and a deliverence expert? Will she and Lol finally make a public go of things?
