From the Introductions:
AN ADVERTISMENT FOR MR. RICHARD A HADLEY
The following missive is a printed copy of one of a series of private letters sent anonymously and without return address to a Mr. Richard A. Hadley in London, addressed in the Autumn of 1883. With the location of Mr. Hadley yet unknown and the letter undelivered, as per written instructions on the envelope, in this the year of our Lord 1891, the letter has been opened and reproduced in good faith in this copy of the Islington Gazette, paid for with enclosed funds.
A love letter to Lovecraft.
Written as a series of mysterious letters from the late Nineteenth Century, published in a local newspaper, these odd games takes the form of esoteric Victorian Parlour games.
Somewhere between a seance, mass hypnosis, and guided meditation, these experimental RPGs are immersive horror games of the best kind.
A sort of paranormal investigation, Dear Mr. Hadley is to role playing games what the Ouija board is to Board games.
