In The Mansion of Madness


A CHOOSE A GRISLY DEATH solo adventure with multiple endings!

For more than a hundred and fifty years, the Night Office has been in your neighborhood. When someone on your street mysteriously vanishes, it is because the Night Office shoved them in a van in the dead of night. When stray dogs go feral, it is the Night Office that gets bitten so your children stay safe. When cats make strange noises at night, it is because the Night Office is standing on their tails.

This Psychological Assessment Exercise puts you on a Night Office field operation team. You are the Closer. It is your job to close all doors, gates, portals, jars, chests, and any other object that might contain a space jelly. Failure to close things properly means people will die. Do you have what it takes to keep humanity safe?


• How to work with a team.
• Or, at the very least, how to suffer the idiots you are forced to work with.
• How to identify space jellies.
• How to navigate the awkward pauses of a failed relationship when you and your ex have to work together to save humanity.

Intended for solo play, this adventure is reminiscent of old school text-based adventure games. All the decisions are yours, and there are so many ways to die—usually horribly. It's old school choice-driven role-playing!

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
