Synopsis: From the back cover of the Ace first edition: More than a doctor, more than a detective... He is Sir Adam Sinclair: nobleman, physician, scholar - and Adept. A man of learning and power, he practices ancient arts unknown to the twentieth century. He has had many names, lived many lives, but his mission remains the same: to protect the Light from those who would tread the Dark Roads. Now his beloved Scotland is defiled by an unholy cult of black magicians who will commit any atrocity to achieve their evil ends - even raise the dead! Only one man can stand against them... The Adept.
