The reader is a character in the story, invited to guess the identity of the killer each week. The Murder in the Mail forums are a place where readers can compare clues and insights, helping (or hampering) one another. Everything, including the art, contains clues to be unravelled.
The story is A Bloody Birthday,which was originally sold in 'mail-out' format. There are a small number of original-style packets containing the full story, but you need to email MurderInTheMailStories@gmail.com to arrange to receive a copy. They cost $70 including postage.
This trailer was made for the original version:
A group of art students gather at a birthday party where the guest of honour, your cousin, is murdered. One of the group is the killer.
You ask the guests to write letters to you, talking openly about what happened, and sharing art works they’ve done in the period of time before, during, and after the party.
People say artists show their soul through their art. . . now it’s up to you to discover the darkness inside someone you trusted.
There are eight beautiful pieces of art included with this story, all made by Australian artists (almost all of whom I scouted out personally here in Canberra). Every character is written by a different published Odyssey Books author (including Tash Turgoose from the Publisher Obscura imprint).
So if you buy this book you get a story, a puzzle, an art collection, and a sampler of Australian authors.
