When Dunbar is sent to Edinburgh to confirm the deathbed confession as a hoax, amongst the confusion, incompetency and deception that he encounters there, a new fear arises: what if the confession is true? A case that has already destroyed so many lives is forced to reopen. Dunbar is determined to discover the truth, even if it is finally revealed to be more horrific than anyone could have imagined...
