Judith couldn’t tear her eyes from the article, and the photo of her that stared out at her from 1970. She’d been twenty-seven years old, and she remembered the day the photo was taken as though it were yesterday. It had been snapped on the beach at Paleokastritsa, after she and Philippos had had lunch. Despite the awfulness of her life at the time, Judith had been unaccountably happy that day. It had been so sunny, the setting so beautiful, and she remembered the early afternoon breeze on the beach that brought the woody barbecue smells of the café mixed with the sweet scent of the rosemary bushes that grew around the bay.

Judith believed that even though she was an old-age pensioner, she still had beauty. But it was a feeling she now carried inside her, rather than being any kind of outward appearance. As she’d got older, her beauty had retreated from her skin and become part of what she thought of as her soul. But she couldn’t help looking at the woman in the photo and noting how very glossy her hair was. How her skin seemed to glow with light, even in the black-and-white photo, and how bloody thin she’d been.

And it was as she remembered how she’d looked when she was in her twenties, that Judith worked out the answer.

The notion popped into her head entirely unbidden. Unwished for. One moment the answer to the puzzle didn’t exist, and in the next moment, it did.

Judith was stunned. Was it really that simple?

And then she felt a sudden rush of adrenaline as she realised the significance of a comment that Andy Bishop had made to Becks towards the end of their walk together.

Judith let the newspaper in her hand drop to the floor, left the room and locked the door behind her. Because her breakthrough was only one piece of the jigsaw puzzle, wasn’t it? There was still a piece missing. But this time she felt confident she’d find it. She knew the shape of the piece she was looking for, even if she didn’t yet know what it was.

In her mind, Judith started going through all of the information she’d learned in the police station: Iqbal’s dreams to buy a boat; the testimony from Fred the postie that Stefan was a crook; the fact that Liz had got a rogue vet to kill her otherwise healthy dog. But no matter how much she tried, the answer she was looking for didn’t jump out at her. She knew she’d know it when she saw it, she just had to keep going.

So where else could she look?
