From the bustling gold rush and the streets of Melbourne in 1864 to the ancient city of Edinburgh in Scotland, Major Findo Gask, his Sherlockian friend, Errol Rait, and their companion Mary Mitchell, flee from a secret society out for revenge. 

While in hiding, Gask visits a second-hand bookshop which launches him on a puzzling trail with deadly consequences. 

Our heroes find themselves pitted against the full might of the British Empire’s secret services and a centuries-old Knights Templar Lodge of the Freemasons with a secret to guard and an explosive plan to replace Queen Victoria on the throne with the true King. 

Murder, kidnap, torture and death stalk their trail. 

Gask and Rait alone have the key to avert a constitutional crisis and the violent conflict that would follow. But can they survive to unlock the puzzle?
