Canaries on the Picture

An Unnatural Visitor
A Startling Sight
Two live canaries perch on a picture frame in Floretta’s room. The sisters have never kept birds and cannot explain how they entered.
A Mystery Within the Mystery
Nancy releases them outside but keeps the incident in mind. The birds’ presence suggests an intruder may have transported them through some concealed route.
Nathan’s Bird Collection

A Suspicion Gains Shape
Neighbors Describe the House
Rosemary and Floretta tell Nancy that Nathan keeps many birds, including canaries and parrots. The detail gives Nancy a possible source for the birds.
A Practical Inference
Nancy does not treat the match as proof, but it makes Nathan’s connection to the strange event more plausible. She begins planning a visit to his home.
The Bird Room

A House Full of Clues
Living and Stuffed Birds
Nancy enters a room containing cages of canaries and numerous stuffed birds. The collection confirms that Nathan’s household could supply the birds found at The Mansion.
A Dangerous Discovery
A parrot squawks and nearly exposes Nancy. The room offers evidence, but its noise also brings Nathan’s servant toward her hiding place.
A Clue to the Passage

A Hidden Room Within a Room
The Closet Refuge
Nancy hides in a closet behind the parrot’s cage as the servant searches. A small knob presses into her back, catching her attention.
From Bird Clue to Architecture
The knob activates the hidden wall and reveals the steps. The birds lead Nancy to the very mechanism that explains how they could appear in The Mansion.
A Detail in the Confession

Evidence in Context
The Bird Room Confirmed
Nathan admits that the hidden passage opens into the room where he keeps his birds. His statement confirms Nancy’s route through the house.
The Case Becomes Complete
The birds alone would not establish the thefts, but combined with the passage and recovered property they form part of a coherent account of Nathan’s access.
