I just read about this on Simon Rogers’ LiveJournal blog:
All of our GUMSHOE PDF products are on sale over at rpgnow.com at a 15% discount until 19th March. Our average rating over 22 reviews is over 4 out of 5. So that’s Trail of Cthulhu, Mutant City Blues, Esoterrorists and Fear Itself. Get them while you can!
I just LOVE the GUMSHOE System, and so I took the opportunity to get the Esoterror Fact Book for just $12.71! If you haven’t done so, you should at least consider getting the core rulebooks for Esoterrorists, Trail of Cthulhu and Mutant City Blues. They are definitely worth it!
Thank you so much for the plug – it popped up in my google alert.
You're welcome!
