A more apt title for the book would be Friends File since it is a not a cold case at all, but a favour for a friend. Even better, for the sake of the reader of this series, it could have been the Final File.
The book starts in the typical fashion of taking the reader through another lengthy revision of most of the main characters backgrounds which readers of the series have already been besieged with countless times. What is missed in the first chapter is infiltrated within the remainder of the books text, with an obvious intent to include every previous character despite their otherwise lack of importance to this story.
Considerable content of the books text is focused on food. One could be excused for thinking that it was more a food blog rather than an investigation. Neither does it appear that any of the main characters ever prepare meals at home. A luxury usually attributed to the wealthy or lazy.
All unnecessary content which merely assists in filling pages of the book without conveying a story. This does not occur until about 20% into the book. Then, the vast majority of the story is about stolen cars which, apparently almost never happens on the Isle of Man, but does very conveniently for the author, manage to happen twice in the space of a week. As stated by Aunt Bessie, talking about Jack Flowers (which the story was supposed to be about), “He’d been rather forgotten because of Charles’s stolen cars”.
