While the first Polaroid from chapter 4 is not shown, it is mentioned by Raymond during the following conversation with Simone Lemorne (Bernadette Le Saché) - the man who abducted Saskia at the service station.
Simone: True, I don't like the idea that you know my name. I have to limit my risks. But you could have traced it from the license plate. You won't gain anything from opening an investigation.
Raymond: The coins from the coffee machine. Your prints are on them.
Simone: If I'd being thirsty, and if I'd had a coffee, I'd have held the coins by the edge.
Raymond: Your on a Polaroid I took at the gas station!
Simone: That's a lie. You would have recognized me at the cafe in Nimes. I was there.
Raymond: Second table on the right.
Simone [After a pause]: Passport.
1. The first still from chapter 4 shows the the Polaroid Raymond Lemorne (Bernard-Pierre Donnadieu) takes as he waits for Saskia Wagter (Johanna ter Steege) to return from the service station, writing on the lower white border: 'Car getting used to Saskia!' - for they have previously decided that Saskia will drive for the final leg of the journey. While Raymond is shown taking the Polaroid camera from the car, the actual taking of the image is not shown - however, it is audible.
2. In the subsequent two stills from chapter 4 (Saskia has still not returned to the car) Raymond is showing the woman at the till in the service station a Polaroid of Saskia, asking if she has seen her (the taking of this Polaroid is not shown and can be assumed to have been taken prior to the events depicted thus far). What is interesting here - and why I have included two stills showing both the front and back of the Polaroid - is that it is of a different format to the other. While the former is either type 600 or SX70, the latter is Image System/Spectra film. Each of which, of course, requires a different camera.
In the preceding scene Raymond shows the Polaroid to two men, asking: 'Excuse me, have you seen this woman?', one of whom states that he saw her by the entrance to the service station. Returning to this location Raymond says to himself out loud: 'If she was here with the cans, then she was on her way back. So she must have seen me. Which means I could also see her. The Polaroid!.'
3. The fourth still from chapter 4 again shows the Polaroid of the car. Raymond is showing the Polaroid to a supervisor, saying: 'Look! Here she is. Here, the little red dot. See? It's her. It can't be anyone else. And there's somebody here, beside her. We've got to find him!' Of course, figures are difficult to distinguish.
4. The still from chapter 7 shows the poster soliciting information as to the whereabouts of Saskia, and while not a copy of the Image System/Spectra Polaroid shown to the woman at the till, bares similarities. Indeed, on first viewing I took it to be a copy.
There are a number of differences between the film and the book, most noticeable is that the type of photograph shown to the woman in the service station is not specified, it is described only as a 'picture' (p18), 'photograph' (p19) and 'snapshot' (p19). The picture mentioned on p41 could possibly be the same photograph also.
