Copying A Master

Maurice, an idealistic painter, is pulled into an art fraud against his will by a friend. It is the time when Austin Spare was alive, and the premise of this book is that artists had already been painting magical sigils for millennia. So Maurice seeks a solution to his problem through a sigil spell.
Meanwhile the crisis of the fraud uproots him, wrecks his domestic life and drags him across three European countries as he flees the revenge he fears. The true definition of a master is gradually revealed.
