The Party to End All Parties by Lucy Roth

 A guest was murdered at their party...

So they hid the body in the wine cellar.

The Morland siblings are rich, privileged, and completely dysfunctional.

After throwing one of their legendary parties at the family estate, they wake up with hangovers...

and a dead guest.

Instead of calling the police, they make a terrible decision:

They hide the body in the wine cellar.

Now each sibling suspects the others.

Old rivalries explode.

Family secrets resurface.

And an upcoming inheritance inspection threatens everything they stand to gain.

As paranoia spreads through the mansion, strange things start happening.

Including one very unsettling detail:

There's knocking coming from the wine cellar.

Because hiding a body is one thing.

Living with the consequences is another.
