Two of London's sharpest minds within the Peculiar Crimes Unit are faced with one of the most befuddling and bizarre cases of their careers as an ill-timed death, a powerful curse, a crazy dowager and a dead photographer lead them into a world of madness, codes and the secret of London's strangest relic.

It is 1969.
