In the summer of 1849, Patrick O’Connor, a prosperous London customs officer, vanished without warning. His trail ended in a quiet Bermondsey house, home to Frederick and Maria Manning—a married couple bound to him by secrets and suspicion. When O’Connor’s body was found buried beneath their kitchen floor, whispers of greed, betrayal, and hidden passions spread across London.

![Sadamichi Hirasawa & The Teigin Incident
Tokyo, Japan, 1948. A man walks into a bank, announces himself to the manager as an official of the local Government Health Department, instructs the staff to take an inoculation medicine and walks out leaving 12 of them dead from poison. Upon first hearing an overview, this might sound like a somewhat unique, but trivial bank robbery. But this is post-war Japan, a country with many secrets and a population with many grievances.
