The Many Deaths of Edward Bigsby

From publisher blurb: "Praise be to Her!" is the last thing Bigsby says. But who is Bigsby? What does he want? Why would anyone want to kill him? These are the questions you must answer, and quickly. Else you might find out what's hiding behind the Green Door... A Trail of Cthulhu scenario, compatible with Bookhounds of London, by the author of Pelgrane's Not So Quiet, Sisters of Sorrow, and other chilling tales!
