In a Bookhounds of London campaign, the Investigators do not investigate horror and strangeness professionally. Rather, they investigate books about horror and strangeness and become, seemingly inevitably, drawn into the horror themselves. If they could just sell a pristine copy of the 1845 Bridewell edition of Nameless Cults, pocket their 40% (or 400%) and move on, they would. But it's never that simple. Not for them. Not for book-hounds. Not in London. Not now. Featuring 32 authentic, full colour maps of 1930s London, an extensive index, new Drives and Occupations, and a brand new sample adventure, Whitechapel Black-Letter, this is a must for any Mythos investigator.
