This engaging mystery story is an easy read, and has a fast moving plot with plenty of action. The tantalizing tale of the lost relic discovered by the Templar knights found at the location of a tunnel under the old ruins on temple mount just before the lost battle of Jerusalem sets the stage for a centuries old secret. At the time of the Templar's final betrayal by the King of France, the relic was secretly hidden in a little old chapel near Wales. Now many centuries later, Scotland Yard detective inspector Owain Wallon, who uses the Welsh spelling fo his name, struggles to bring his murder suspect involved in a drug cartel's raid back in London, following a terrorist attack in New York City. While returning to London, he becomes embroiled in the drug cartel's scheme to kill his prisoner. As the mystery unfolds, Wallon finds himself under constant attack by the cartel which is attempting to wreak revenge on Guy Pentwyn Lydley. Entwined in the search for the relic location by the Lydley family and his own Gorwyn family, he strives to solve both the crimes and the mysteries. Also included in this book at the end is the first chapter of my next book which has some of the same characters involved in another mystery which takes place in Snowdonia Wales,"Gold Mine in Wales Vandalized."
