Directed by Roberto Pariante (who was the assistant director for Argento on The Bird With the Crystal Plumage, The Cat o’Nine Tails and Four Flies On Grey Velvet) and Dario Argento, who wrote the script with Luigi Cozzi, Testimone oculare is my favor episode of Doorway to Darkness. It’s so simple and yet succeeds as an example of giallo.

Roberta Leoni (Marilù Tolo, Las trompetas del apocalipsis) is driving on a dark and rainy night when she sees a woman dive in front of her. She doesn’t hit her, but does find her dead body. She’s been shot in the back. That’s when she sees the glint of a gun and runs through the storm to a diner where she breaks down. The police, led by Inspector Rocchi (Glauco Onorato), take her back to the crime scene but there’s no body and no blood.

Everyone treats Roberta like a hysterical woman, including her husband Guido (Riccardo Salvino), even after someone breaks into their house while they’re out for their anniversary and the next day when someone tries to shove his wife into traffic. Then the phone calls start and never seem to stop.

One night, while all alone, the killer calls and says that they will finally kill Roberta. Guido comes home just in time and says that instead of leaving — the killer cut the phone line — they are going to wait for them and he will shoot whoever is after her. As you can imagine, this isn’t the way things end up happening.

Sometimes, a simply told mystery is exactly what you need. That’s what this episode gave me. Supposedly Argento disliked the work that Pariante did and went back and filmed a lot of this himself — the tracking of the killer by footsteps is definitely him — and then not putting his name on it.
