A Map Before Questions

Preparing to Ask
The Street Recorded
Christopher draws a map of Randolph Street before approaching neighbors. Knowing the layout helps him decide who might have seen Mrs. Shears’s garden.
He carries his Swiss Army knife because he feels safer with a familiar tool.
Bravery as Method
Talking to strangers is difficult for him, but he treats interviews as necessary detective work. The map turns an intimidating social task into a planned sequence.
The Wrong Thompson

An Interview Goes Awry
An Unexpected Identity
Christopher knocks at number 40 expecting Mr. Thompson, but Mr. Thompson’s brother answers. The man has no useful information and questions whether Christopher should be investigating.
Christopher persists in asking about Wellington and the night of the killing.
A Limited Result
The interview produces an alibi claim, not a clue that can solve the case. Christopher thanks him and moves on.
Warnings from Number 44

Caution Without Answers
A Neighbor’s Concern
A woman at number 44 has heard about Wellington but saw nothing suspicious. She suggests Christopher speak to Father(Ed Boone) and tells him to be careful.
Christopher explains that Father has told him not to investigate, revealing the secrecy of the project.
Evidence Still Missing
Her warning does not answer the murder question. It does, however, show that other adults see risks Christopher has not fully considered.
The Wise Encounter

A Joke Misfires
An Unhelpful Response
Mr. Wise laughs and makes a remark about young policemen when Christopher asks who killed Wellington. Christopher dislikes being laughed at and leaves.
The exchange shows how teasing can end a conversation rather than establish friendliness.
A Social Limit
Christopher continues the investigation elsewhere instead of trying to interpret the joke. His approach favors direct answers over ambiguous banter.
Mrs. Alexander’s Partial Clue

A Neighbor Becomes a Source
A Careful Conversation
Mrs. Alexander answers Christopher’s questions and attempts friendly conversation. She knows of Wellington’s death but cannot identify the killer.
Christopher leaves before she can bring him tea, still uncertain whether he can trust a stranger.
A Suspect Emerges
On the way home, Christopher reasons that Roger Shears may have wanted to upset Mrs. Shears. Mrs. Alexander later reveals a family secret, but not a proof of the murder.
