Picked this one up recently - billed as comic farce.
From the Blurb:
A desolate valley.
A missing mathematician.
A glamorous and beguiling council bureaucrat with a hidden past.
A cryptic map leading to an impossible labyrinth.
An ancient conspiracy; an ancient evil.
A housing development without proper planning permission.
All leading to the most mysterious mystery of all.
Mysterious Mysteries of the Aro Valley is a dark and forbidding new comic farce by the author of Unspeakable Secrets of the Aro Valley.
