The Bone Charm Situation is a book found in Dishonored.
[Excerpt from a report to the Office of the High Overseer Gerard]
I was asked, should we not tolerate the possession of simple bone charms among the populace? Surely this is a trivial matter, merely a cultural practice seen across the Isles? Not as terrible as the creation and coveting of more complex occult runes?
Such an insidious question.
This foolish distinction weakens our mission while the stench of the Outsider grows thick around us.
Perhaps, as some claim, our ancestors tolerated these cursed practices during the times before our modern Empire arose, to ease the lives of the lowliest serfs as they paved the roads to civilization. But there is no excuse for witchery in this brighter industrial age.
Having adjudicated the trials of many heretics myself, I swear that their eyes, as the clarity of pain took their lives, were grateful to be liberated.
The book can be found during the final part of the mission High Overseer Campbell, in a building near the fenced area of the Backyard that must be accessed from a second story window. The first story yields a pack of plague rats--the book is on a table next to a bone charm stuck inside a vice. The table can easily be reached without dealing with the rats by either jumping or blinking from the chain Corvo Attano climbs down on.
