One night of revelry. One last chance to save Ironwic from a horror hiding in plain sight.
In the final explosive chapter of the Ironwic Mysteries series, your players must sneak aboard the airship Reichenbach to stop Moriarty from ensnaring the city’s elite at a masquerade ball, where danger lurks behind every mask.
The Ironwic Mysteries adapt the best of The Adventures of Sherlock Holmes, The Case Book of Sherlock Holmes, The Memoirs of Sherlock Holmes, and other classic tales into 5e mystery adventures set in the gothic, steampunk city of Ironwic.
This climax to the series is an homage to The Final Problem. For those familiar with that fateful showdown, you know it was a dance of wits where one wrong move meant death. Here, that fatal dance is revived as a masquerade ball on a glittering airship. Only this time, your players have a shot at changing the ending… if they can survive long enough.

The Story
The Reichenbach airship is a sight to behold—a metal behemoth floating above Ironwic, filled with the city’s elite who have come dressed in masks and finery. But these guests don’t know they’re stepping into a trap, woven from threads of cunning by the arch-vampire Moriarty, who plots to make the city a haven for his kind.
Only your players stand in Moriarty’s way. Charged with fulfilling the last wish of the late Sherlock Holmes, they’re tasked with uncovering Moriarty’s true identity and stopping a bloody conquest.
Grab your copy of The Reichenbach Ball and invite your players to the masquerade—if they’re brave enough to face what’s behind the mask.
