Sidney reviewed Haunting Shades of Grey – Haunting Shades of Grey 17 January 2011 Haunting Shades of Grey is the latest addition to this Series with Mai Griffin excelling herself yet again. In this latest story Mai takes you on a journey of mystery and suspense with the skill of a Mistress of the written word, and keeps the mystery going to the end. Mai has again used her native tongue to very good effect and ‘Haunting Shades’ is an excellent partner to the previous books in this Series. It also interesting to note that this book, and the series, are set on the edges of recognisable locations in England and Spain.
