The Sister Story

The Sister Story
A fabricated account
Brigid says her sister has run away with Thursby, framing her request as a family emergency.
Truth withheld
The story recruits Spade’s help while concealing the falcon. Its eventual exposure teaches him to examine what the client’s performance is designed to obtain.
The Discarded Clue

The Discarded Clue
Newspaper fragment recovered
Spade finds part of a shipping list in Cairo’s wastebasket and compares it with a complete copy of the paper.
Inference checked
Rather than rely on Cairo’s account, Spade reconstructs the missing information and follows the ship named in the notice. The method makes evidence answerable to comparison.
The Conflicting Accounts

The Conflicting Accounts
Accusations multiply
Brigid and Cairo each claim the other attacked first when the police enter Spade’s apartment. Spade offers a comic account that neither fully describes what happened.
A practical fiction
The officers cannot easily establish the truth from the participants’ stories. The episode shows that an agreed lie can temporarily protect people even when everyone knows it is false.
The False Bird Tested

The False Bird Tested
An object examined
Gutman cuts through enamel and into the statuette rather than accepting its appearance or its historical story.
Physical evidence settles the question
The metal proves to be lead. The test defeats the claims of every person who expected the delivered object to be the treasure.
A Confession Reconstructed

A Confession Reconstructed
Motive and method confronted
