Watchers Of The Dead, Simon Beaufort, HC/DJ Severn House 2019 British Mystery.   Ex library book but it looks like it has not been read.  It has a  stamp on the top textblock.  See photos.  The dust jacket has small piece cut off the edge where a magnetic ID strip has been removed.  A nice clean book apparently little used.  If you like action-packed Victorian age mysteries, this is for you.
