This is a very Noir-ish mystery with some great experimental cinematography about two detectives trying to solve the murder of a local, what looks like a Bunker Hill neighborhood business man. A nightmare sequence features the iconic (for Film Noir) Bradley Building in LA.
I was pleasantly surprised, the film was produced by Futuramic Productions whose only other efforts were Squad Car (1960) and Come Spy with Me (1967). Arlene Sax plays a beautiful but troubled woman living in a low rent rooming house who thinks she shot the intruder. A beatnik artist is the only witness. Sax, later known as Arlene Martel, was a staple of 50s-60s TV. A 7/10 worth a watch for Sax/Martel fans. If you were alive in the 60s and watching TV she did many guest shots.
