01Opening cycle
Immersion
The series establishes a broad Whapperton field of suspects, performers, observers and unexplained pressures. It is a beginning in the technical sense only.
02Event file
The Killing
A Memorial Square sequence gathers the largest recorded cast. Whippy is the one absence consistently retained after the competing drafts are compared.
03Unresolved
Fallout
The archive repeatedly announces an aftermath episode, with prosecutions, alliances and further arrivals proposed. No settled version was broadcast.
Where the serial spreads
Further regulars: Ainsley, the Frainstone Variant, Mbotwe, Sweetman, the Marceau Mob, Jedson, Salmon, Harriott, Boross and the Calypso Twins. The consistent geography is equally important: Phil Collins Memorial Park, Memorial Square, Masks, Mike's, Vegetables, the Knopfler Underpass and the north moors.
Later material: a 1950s origin idea, A Thacker Calls, and a fourth-season return are both noted, but remain developments rather than a completed continuation.
