THE
STREETS
Geography & Crime Crawl
Detroit was worked block by block. Streets led to precincts, factories, taverns, homes, courtrooms, and cases. This section connects Ralph Palmer's chronology to the physical city beneath it.

THE MAP ROOM
Two ways into the same city.
One view follows the street grid and old maps. The other treats the chronology like an investigator's working board: locations, dates, cases, and connections. Both remain anchored to verified geography and chronology.
THE STREET MAP
Trace Detroit.
Period-map atmosphere, major arteries, neighborhoods and documented locations. Red routes can follow the streets that carry the chronology.
OPEN MAP →THE INVESTIGATION BOARD
Connect the files.
A period-inspired case board: pinned locations, dates, police units and strings that show relationships without turning history into fiction.
OPEN BOARD →THE STREET MAP
The city becomes evidence.
This first map is deliberately schematic. Documented streets, addresses and period maps govern the historical geography; invented locations do not.
THE INVESTIGATION BOARD
Pins. Dates. Connections.
Not a Hollywood conspiracy wall. A restrained, period-inspired research board that lets visitors see how a place connects to a case, a police unit, a newspaper date and a chapter.

THE WORLD KEEPS OPENING
One address can lead anywhere.
A street can lead to a neighborhood, a case, a newspaper, a police unit, an archive item and back into the book. That cross-linking is the engine of Crime Crawl.
