John and James: the difference is evidence
A cross-series framework for separating resemblance, behaviour, knowledge and the assumptions made by everyone around the Taylor twins.
Reviewed guide · Sources & corrections
How John inhabits the role
Speech, confidence, eye contact, police procedure and social ease create tests that appearance cannot answer. Record a difference only when it is shown or stated.
Follow John’s file →The most dangerous gap
John can imitate a face but cannot automatically possess James’s professional relationships, private conversations or recent decisions.
Follow James’s chronology →Who notices—and when
Track what each person believes, what they suspect, what they can prove and whether they act on that knowledge.
Open the knowledge tracker →Puzzle-setter outside the police world
John enters the story with pattern and constraint expertise but incomplete knowledge of James’s work and recent life.
Compare puzzle methods →The absent centre of the long case
James is represented through family testimony, professional traces, the notebook and the consequences of his disappearance.
Inspect confirmed evidence →Evidence rule
Observation, character belief and audience knowledge remain separate. No private history or intention is invented to fill a gap.
