Opting for a fair amount of character development and a solid plot, the author has created a thoroughly enjoyable book that I completed in one sitting. Avid mystery readers will probably ID the killer about half way through the book.
The supposed similarity of this book with those written by Minette Walters must be owing to plot elements such as: three suspects and a body found in water (the Breaker); or, a long dead body that brings a formerly frustrated cop back to harass the main suspects (The Ice House). However, the depth of character development found in Walters' better books is missing. And, the reader probably won't learn much from this book, unlike those by Deborah Crombie (last two), Minette Walters, or P.D. James -- or even Elizabeth George for that matter.
The book reads like a screenplay -- which should be appreciated by TV buffs. Each chapter is an act, containing a 'scene or two. The set descriptions are good, although are a bit misplaced, i.e. the setting sun as mango hanging in the sky dripping juice at the soon-to-be death scene might have worked better in the scene where Cora was thinking about her long-dead RAF lover.
The writing in "Likeness in Stone" is not as rich as text by P.D. James, however, the plot moves along at a reasonable clip to a solid ending. In some of her books, James lingers over detail at the expense of a tangled ending, although she seems to have overcome that in her last two books.
