Two new pics have been posted to Photos relating to a location used in "Let Us Prey."
Map for Search: "Let Us Prey." The Cafe Madrid scene was filmed at Columbia (now Warner) Ranch. This was where Bianco met Fuentes, and where Fuentes was kidnapped moments later. This area was a stone's throw from the Parker house of "Countdown to Panic" on the Blondie Street of the Ranch. (The Convent area of the Ranch no longer exists.)

Matchup photo for "Let Us Prey," the Cafe Madrid scene where Bianco met Fuentes, then Fuentes was kidnapped. The two main buildings of the scene are visible in both pics, only the perspective is different. Note the details of the buildings, the number of arches, the placement of windows, etc.
You can find a previous photo I posted, the overhead view of Warner/Columbia Ranch and the Parker house from "Countdown" and see that beyond the "backyard" of the Parker house, the Convent set area no longer exists. Today it is devoted to parking and storage, etc. Back during the late 1960's, the Convent area was used by series such as "The Flying Nun."
