In this, Thurbin’s 15th book in the series, Professor Ralph Chalmers and Katie find themselves caught up in the refugee crisis facing Europe as Colonel Stigart enlists Ralph’s help to track down the criminals who are engaged in human trafficking. Ralph has to balance winding up his job at the University, commitments to the Colonel, his upcoming marriage to Katie and preparing Gypsy Lady for their world voyage after the wedding. This heady mix forms the background to a fast moving contemporary thriller that takes the reader from Tunisia to France, and from Munich’s red-light district to Biggin Hill, the disused WWII RAF base in the Kent countryside. A country mansion in the Cotswolds becomes the setting of some daring-dos as our intrepid pair struggle to apprehend the criminals. For the reader who likes the tension of a chase and the lengths to which people will go to for money and power, this book is a sure winner.
