Razor's Edge

An invitation to a fancy dinner party with the eccentric madam of the estate. What could better?
Strangers gather at the estate excited to have been invited to the dinner party. No one bothered to inquire why they were even invited. No one new anyone and, more importantly, no one new the madam.
It seems too good to be true. The dinner guests will soon learn that sometimes an invitation, no matter how extravagant, should be declined.
A horror novelette.
