Three London gentlemen return to Marisdùn Castle this fall for another haunted Samhain masquerade. Lord Quentin Post is still in pursuit of his angel. Mr. David Thorn is searching for his artist. And Mr. Sidney Garrick is still on a quest for more than just a little fun.
But when a powerful entity is accidentally released inside the castle walls, all bets are off and the lives of the three gentlemen in question will never be the same again.
