Thirst for Blood - An Interactive Murder Mystery Game

Susan Haley

Published by Haley Productions

This is set on Halloween during the annual Devil's Gulch Costume Ball

It was one year ago tonight, at the very stroke of midnight, under a full harvest moon, that a fire broke out at the Bates Mansion situated next to the historical cemetery at the edge of town

Witnesses to the fire say they saw the mansion spontaneously combust into a terrifying ball of fire and, as it burned, they saw distraught ghostlike beings fly out of every window, wailing in terror

Today the Bates mansion still lies in ruin at the top of that hill - an eerie reminder of that tragic night and of the curse that seems to hover over this town ...

8 PRIMARY SUSPECTS (they will have full knowledge of the mystery & be given a complete script):

GRACE PEABODY: Reclusive and eccentric occultist who's come out of hiding to warn Devil's Gulch that something evil is about to happen again. She'll do everything in her power to stop it

LESTER DANVERS: Folks around here call him 'Simple' Lester because he hasn't been the same since he almost died in that awful fire last year. He seems to have a big crush on Lucy

LUCY CABOT: A woman who devotes too much time to her career as a writer for the 'The Probe' newspaper as she searches for someone to mend her broken heart (her fiancé was lost in that tragic fire). She's hoping that man will be Peter

HELENA WASHINGTON: She's domineering, powerful and very much a nag to her husband, George. Oh, and Peter Parker is the bane of her existence

MAYOR GEORGE WASHINGTON: George is very proud of the fact that he was named after our first president and considers himself comparable to his namesake. Truth is, he needs to prove himself a man, especially with his wife

PETER PARKER: The wealthiest man in town with the bad boy reputation. This man always gets what he wants and he wants the Bates' property so he can build a large mall and wax museum!

INGRID BATES: Norman Bates' alleged long-lost aunt who has come to Devil's Gulch to lay claim to the mansion

DR. LUDWIG VON HERRING: He investigates the unusual and the unexplained and plans to use the mansion as a center for the paranormal

SECONDARY SUSPECTS (Optional. Remember, EVERYONE will be actively involved in this mystery because it will be their job to solve the case and because you'll be encouraging them to come in costume and in character. Use any and all of these secondary suspects if you have "extra" cast members you want to use. You will NOT give them a script but you will give them a description of their character and let them run with it):

Clinton Bush: A slick and smarmy know it all running for mayor against George. He enjoys the game he's playing with George who he clearly thinks is a weak leader and forgettable sort of human being. George needs to prove him wrong

Penelope Parker: Peter's ex-wife. She's here to make sure she gets what's coming to her from her miserable ex-husband

Winston Cupp: Peter's lawyer. He can run interference for and support Peter. Cleo Lane: Grace's apprentice who helps her with her exorcism/séance

Renfeld: Ludwig's enthusiastic assistant who can't do enough for his mentor. You can also include: Relatives of the primary suspects or of the men who died in the fire. Supporters of the Paranormal Center. Supporters of keeping the land as it is and keeping the cemetery where it stands. The owner of "The Probe", the newspaper that Lucy works for

These audience-participatory Murder Mysteries are distinctive in that everything from arguments to clues to the actual murders happens in the middle of the audience enabling them to participate and witness every action first hand. None of the dialogue is scripted - it's all improvised - the role of the guests is to actively solve the case by asking the suspects questions, following them, eavesdropping on their conversations, and so on - whatever it takes to discover whodunit

NUMBER OF PLAYERS - Up to 125 plus the Primary Suspects (your cast)

LENGTH OF MYSTERY - Approximately 2 hours.

HOW IT WORKS: You'll need to provide 6-8 people willing to take part in the mystery as the primary suspects, victim(s), detective and killer (see below). They'll have full knowledge of the script, which means they'll know "whodunit". The rest of your guests will take on the role of Detective and it will be their job to solve the case. Everyone, therefore, will have a crucial part in the mystery. The game lasts about 1 ½ to 2 hours but you can, of course, make it longer by allowing more time between the scenes/action

Your guest actors won't have to memorize a lot of dialogue but they will have to be familiar with a sequence of events or timeline that will move the mystery through the clues, the murder(s) and the solving of the crime. They'll also have to carry out certain actions (like arguments) and suspicious activities to set themselves up as Primary Suspects

NB - This type of mystery game is geared towards groups of 15 or more. All scripts are rated PG-13, contain adult themes and may not be suitable for children


Upon arrival, the guests receive a program that will be a guideline for the mystery (included in this package). The primary suspects start to mingle in character, usually during the reception, and begin setting up the mystery with clues, arguments, gossip, that sort of thing. Just about the time the first course is served, the guests witness the (1st) murder. The mystery continues to unfold with more dramatic action and more clues that will lead to the mystery's conclusion. The "detective" character then allows the guests to asks his primary suspects any final questions and has the guests fill out their detective evidence record (which they receive with their programs). The solution is dramatically revealed around the time dessert is served


1. Program master (you will provide this program to all participants. It will be their guide to the mystery by providing the basic plot of the mystery, the primary suspect list and the "rules" of the game.)
2. Solution sheet master
3. Invitation master
4. Outstanding and Bumbling Detective certificates
