This review was originally published in a slightly different form on RPG Geek.
This is Chaosium's Miskatonic University Library Association Monograph #0346, Farewell, My Sanity, originally published in 2007. The MULA books are limited print run, rough-draft style releases from Chaosium. Their purpose is threefold: one, to test the market on a limited basis to see if there is demand for a wider release; two, to allow authors a quick path to publication in the hobby; three, to save Chaosium money on editing, typesetting, art, etc.
The good news is that you can get more unusual material, or that with limited mainstream appeal, than you would otherwise. The downside is that this is often little more than a step above self-publishing, and they are often expensive compared to official releases in the main line. Farewell, My Sanity is an exception to this at $20 for 120pp, although there is a lot of white space that pads the page count unnecessarily.
Content-wise, this contains two excellent, solid scenarios that capture the feel of both Call of Cthulhu as well as Los Angeles.
Spoilers abound! Players, stop reading now!
