A city has secrets. Someone has to notice.

The work no one sees.

It is 1957. Most people have never heard of The Watch Office. Known within its files as TWO, its detectives investigate the small disturbances that others overlook, quietly connecting clues before they become threats to the safety and well-being of the public.

Every incident enters a private ledger. Some files close in a day. Others reveal a trail that runs through the whole city.
