The blend of horror, investigation and dark humor are well-delivered at The Laundry, Her Majesty's Occult Service.
The writing style is extremely engaging with Pratchett-esque footnotes throughout. The Orientation-style document as preface is used in a refreshing and quirky way and sets up your expectations for this game very quickly.
I had bought this as game that could be used as a palate cleanser between campaigns, but after finishing it, I think it would be an excellent campaign in itself.
It is now sitting next to my West End Games copy of 'Men In Black' and I can't wait to unleash a 'cleaner than clean' campaign un my players.
