By early evening of the same day, Mary Raven had her story. It was complex. She would have preferred to talk to Henshaw, of course. She was convinced that he played a part in it somewhere. But she had evidence enough without him, and she had not tried too hard to find him. She had rattled into Brinkbonnie in the morning, staying long enough to annoy Rosemary Henshaw, then driven on to talk to other people in different places. At the back of her mind all the time there was her concern for Max, and as she drove along, she stared out as if she might see him by chance walking down the pavement towards her. Perhaps the anxiety clouded her judgement because she had no sense of danger.

She had gone to the west of Newcastle to a converted warehouse where an ex-councillor had set up a charitable trust for alcoholics. She talked to the man and all of the residents, as well as an old lady who had lived rough for years, walking from the Scottish borders to the Tees every summer, and who had been persuaded to make her home in this building off the Scotswood Road with its view of the Tyne. Then Mary drove back to Otterbridge to the geriatric hospital and talked to another old lady, her body as fine and frail as a pipe-cleaner doll, her mind as bright and clear as a child’s, her memory perfect. By this time Mary was pushed on not only by ambition but by anger.

When she got to her flat, Mary saw her landlady, who lived in the house next door, staring at her curiously through the living-room window. When Mary moved she disappeared guiltily, so Mary thought: She’s planning to put the rent up again. But the landlady had promised to phone the police as soon as Mary got home. She thought Mary was a nice girl and had never liked the police, so it was a difficult and awkward thing to do.

Inside the flat Mary boiled the kettle, made a mug of coffee, and started in her mind to write her story. Absentmindedly she went to collect her mail from the front door. There was a leaflet about the poll tax, and hand-delivered, still stuck in the flap of the letter box, a note.

“Meet me,” it said. “ Brinkbonnie dunes. Eight o’clock.”

He had signed it with the incomprehensible scribble that could only be deciphered by colleagues and pharmacists.

She stood for a moment in the grimy, ill-lit hall holding the note and staring at it. The coffee mug in the other hand tilted and tipped hot liquid over the carpet and her foot. There was none of the elation she might have expected. She was glad he was safe and had apparently so far avoided arrest, but she was not even sure if she wanted to see him.
