In this second part of Terri Nixon's new series, "The Mists of Pencarrack Moor", the women investigate Xander Nicholls' plane crash from "The Secrets of Pencarrack Moor". They are convinced that his plane did not accidentally crash in the bay, but that he was the victim of a conspiracy. One theory is that his instructor survived the crash and escaped abroad.
Meanwhile, some clay quarry workers in the region want to form a union, with the aim of forcing their new boss out of work. He prefers cheap materials over the safety of his staff, and they do not want a repeat of what happened a few years ago in a mine at another location; five people died there.
The book jumps back and forth between these two storylines. There is also some overlap of some of the characters. It's quite an extensive cast, and I really had to pay attention not to confuse them with each other. At the front of the book there is a - limited - list of names of a number of characters that we already knew from previous books, but this story mainly revolves around new characters that do not appear in that list.
I did miss the more thriller-like atmosphere of the previous book. I found this one less playful, less adventurous. The book does follow the same formula: a prologue that takes place some time before the main story, and two storylines that eventually converge. But no special revelations this time.
