The TVI Take

Hitchcock's 1943 Thornton Wilder screenplay (the writer Hitchcock named as his favorite collaborator). Joseph Cotten's Uncle Charlie arriving in Santa Rosa to hide from a serial-murder investigation is the structural inverse of the Hitchcock formula: the protagonist's home is the safe space the antagonist enters rather than the unsafe space she must escape.

Teresa Wright's young Charlie is rare female-protagonist work whose investigative intelligence drives the plot.
