The Newton family home is located at 904 McDonald Avenue in Santa Rosa , which is still standing . The stone railway station in the film was built in 1904 for the Northwestern Pacific Railroad and is one of the few commercial buildings in central Santa Rosa to survive the earthquake of April 18 , 1906 . The station is currently a visitor center . The library was a Carnegie Library which was demolished in 1964 due to seismic concerns . Some of the buildings in the center of Santa Rosa that are seen in the film were damaged or destroyed by earthquakes in 1969 ; much of the area was cleared of debris and largely rebuilt . The film was scored by Dimitri Tiomkin , his first collaboration with Hitchcock ( the others being '' Strangers on a Train '' , '' I Confess '' and '' Dial M for Murder '' ) . In his score , Tiomkin quotes the '' Merry Widow Waltz '' of Franz Lehár , often in somewhat distorted forms , as a leitmotif for Uncle Charlie and his serial murders . During the opening credits , the waltz theme is heard along with a prolonged shot of couples dancing
