Paris Headquarters

Paris Headquarters
A Quiet Telephone
Jules Maigret expects calls after Louise’s photograph appears in the papers, but receives almost none. He assigns Inspector Janvier to test clothing evidence and sends Torrence to hotels and women’s hostels.
Parallel Searches
The inquiries spread across ordinary institutional channels. Their slow start emphasizes that Louise’s disappearance has left no obvious circle of family or friends who can immediately claim her.
The Laboratory’s Trace

The Laboratory’s Trace
Dust and Paint
At the Technical Branch, Moers examines Louise’s clothes and identifies green paint and grains of sand. The material traces do not immediately name a killer, but they suggest that her clothes have passed through more than one environment.
Evidence in Reserve
Jules Maigret considers each finding without forcing it into a premature theory. The laboratory’s quiet work offers a counterpoint to the emotional uncertainty of witness accounts, even when its clues remain inconclusive.
The Nice Inquiry

The Nice Inquiry
A Local Memory
Féret follows a call from a fish seller in Nice who remembers Louise as a child living with her mother. Her memories establish the family’s old neighborhood and the mother’s habit of leaving the girl to fend for herself.
An Investigation Beyond Paris
The request widens the case across distance and time. A woman dead in Paris is now connected to a childhood in Nice, showing that local police knowledge can recover parts of a life missing from metropolitan records.
The Florence Call

The Florence Call
Reaching the Newlyweds
Jules Maigret telephones the Santonis at their hotel in Florence. Marco Santoni initially objects to the interruption, but Jeanine eventually speaks about her encounter with Louise and the letter she received from the concierge.
A Break in the Case
Jeanine recalls the message directing Louise to Pickwick’s Bar. The call supplies a concrete destination and transforms a confusing set of final sightings into a line of inquiry that can be tested.
The Federal Check

Verifying the Past
Jules Maigret contacts Clark at the FBI to confirm Julius Van Cram’s aliases and death in Sing Sing Penitentiary. The international file supports the story that Falconi had tried to exploit.
A Wider Resolution
The call establishes that Jimmy O’Malley’s message and the Brooklyn money were real. The murder is solved in Paris, but its financial consequences stretch across borders and require cooperation beyond the local police force.
