The Vampiric Submariner

When a blood-soaked artifact lands on his desk, mild-mannered archaeologist Robert Atkinson is blackmailed by MI6 into hunting a legendary vampire in Bucharest. But in a deadly case of mistaken identity, Robert finds himself trapped in a maritime museum caught between two undead monsters: one who hates his books and one who loves them too much. It's a race to survive the night using only his wits and a high-powered disco ball. Think Indiana Jones meets What We Do in the Shadows.
