It was the postwoman, who handed her a parcel, got back on to her scooter and sped away up the hill.

The box announced that it was from a large online store. That was strange as Theresa had not ordered anything from them for months.

She crammed the packet under her arm, and started locking up. It was only while putting her keys in her handbag that she noticed the reverse of the wedding photo she had just received.

On the slightly foxed white paper, someone had drawn an ornate red heart pierced with a black arrow.

Sally thanked the lord that the first scene she shot was really simple. She had to walk out of a dark blue door, take a furtive look in either direction and then stride off confidently along a street peopled with extras. She clinched it in one take. The crew moved on and set up location at the boulangerie. Here she had to rehearse taking money from her pocket, passing it to an extra who handed her a baguette, which she stuck under her arm, and again walking off along the street.

On the second section Daniel suggested that Sally take a bite out of the loaf as she walked. She was in a dilemma, as she knew that this was something never done here in France, except by tourists. And as the movie was about two criminals who above all wanted to blend into their surroundings, she felt that her character, Louise, would not do this. Nor was it in the script.

She didn’t want to seem difficult but knew that she was right in refusing to follow Daniel’s orders for the sake of the film’s credibility.

She tried to move nearer to him to explain, but the First Assistant insisted she stay on the spot as the crew was fixing up some supplementary lighting on her.

When the time came for the shot, Sally stepped out of the boulangerie and walked away, baguette tucked under her arm.

‘Cut!’

Everything stopped.

‘Sally, dear. You forgot to take a bite.’

‘That’s the thing, Daniel. I thought that the two crooks needed to be somewhat invisible and look like locals. If I take a bite I’d immediately look like a tourist.’

Daniel sighed.

‘Very opinionated, aren’t you, for an unknown?’

‘I just thought—’

‘It’s not your job to think, luvvie, that’s what I do. OK?’ He made a signal to the First Assistant. ‘Another shot, right away.’

Seething with rage and embarrassment, Sally moved back to the start mark and prepared, on the second take, to dig her teeth into the baguette.

After lunch they moved location again. The scene in the public convenience, where she changed into her disguise, went smoothly enough. There was a tricky moment when one of her false nails got caught in the netting of the wig, but she used it and they didn’t need to do a retake.
