The Vampire in the Iron Mask (The Spinoza Trilogy #3)
By J.R. Rain
Published: November 4, 2012.
In this third and final Spinoza mystery, a worker at a popular medieval dinner theater hires Spinoza to find out the identity of one of his co-workers, a co-worker who's never been seen without an iron mask...and who just might be a real prisoner. As Spinoza investigates deeper, he's about to come face to face with something unexpected...and not human.
