It felt like it was giving off some kind of radioactive glow. She’d stuffed it hastily into an A4 envelope that morning, and the brief few moments of contact had caused a spasm of pain to shoot through her head. She didn’t want to touch it any more than she had to. It was impossible to ignore the thing. Every time she went in her bag to get a book, a tissue or her purse, the bulging envelope seemed to demand her attention. She found herself next to Karis during food technology, washing up some stuff that Mrs Marchment had used in a demonstration. They worked in silence. Tara kept wrestling with the decision to tell Karis about her conversation with Will. Maybe she could take the flipping purse there instead. But something stopped her every time she formed the words. She didn’t want to have to explain how she’d come into contact with Will, in case it meant divulging that she’d been to the lido to find Leo. So she held back.
