I wanna hear your pitches!

Here's mine:

The basement level of the Triple Crown bar has lain empty for years, besides rats, roaches — and the souls of stand-up comedians? Midnight’s marked by the boos and jeers beneath the boards as the ghost of Laurie Sant-Mare, famed comedian, bombs her set before an audience of the dead. The team of investigators will need their wits about them, and a solid tight five, to solve her murder and free everyone from a night of bad comedy. 

Haunted Observatory! Inspired by various space horror things but most especially the X-Files episode "Space" (the one where the astronaut is haunted by the face on Mars. It's great/terrible.)

I'm trying to write one about a haunted music venue. Though to be honest I've focused more on writing a playbook to add to the mystery.
