I bought and read this on release at the end of last year, but have only just realised I never reviewed it. Not sure why, because it's a cracking short novella, tightly paced and plotted, with the genuine creepiness and suspense that all good detective stories should have. Nothing can be taken on face value, especially when your new client - or rather client's spokesperson - Granny Knot is consciously deceiving the general public with a show of craziness, hiding a sharp brain. That she claims to be acting on behalf of a dead man, is something Markhat has to prove for himself  - along with every other story told to him in this yarn.
