From publisher blurb:
Rumors of long-lost smuggling tunnels promise untold riches to the crime family who can locate an entrance. The rising Murdoch clan is convinced that one of these access points is hidden under the old Blackwell family crypts.
But the ruthless Blackwell matriarchs knew how to protect the secret of their smuggling empire with tricks, traps, guardians, and worse.
The crime family sent their best delvers down into Beatrice Blackwell's basement, but none returned. Now the Murdochs look for outside support.
Beneath Beatrice Blackwell's Basement is a trap-heavy module intended for a party of levels 2-3. The traps are all very fun and cool, not 'gotchas,' and there's even a build-your-own-trap-on-the-fly section with advice for the referee. There's a fun mafia subplot that involves searching for the previous victims of the dungeon. There's a surprise faction within the dungeon that upends all plans. Most groups take around two sessions to complete the delve.
