He had spent a great deal of time in the Newmarket pubs going over the ground the regular police had already covered, trying to find out exactly what Paul Shacklebury, the dead stable lad, had known to the detriment of Filmer. No one knew or no one was saying. And who could blame anyone for not risking a quick trip to the ditch.

Millington had had more luck with the hysterical witness, now back home but still suffering fits of the shivers. She, the witness, was a chambermaid in the hotel where Filmer had plotted. She had heard, and had originally been prepared to swear she had heard Filmer say to an unidentified man, 'If he's dead, he's worth five grand to you and five to the hatchet, so go and fix it.'

She had been hanging fresh towels in the bathroom when the two men came in from the corridor, talking. Filmer had been abrupt with her and bundled her out and she hadn't looked at the other man. She remembered the words clearly but hadn't of course seen their significance until later. It was because of the word 'hatchet' that she remembered particularly.

A month after the trial Millington got from her a half-admission that she'd been threatened not to give evidence. Who had threatened her' A man she didn't know. But she would deny it. She would deny everything, she would have another collapse. The man had threatened to harm her sixteen-year-old daughter. Harm he'd spelled out all the dreadful programme lying ahead.

Millington, who could lay on the syrup if it pleased him, had persuaded her with many a honeyed promise (that he wouldn't necessarily keep) to come for several days to the races, and there, from the safety of various strategically placed security offices, he'd invited her to look out of the window. She would be in shadow, seated, comfortable, invisible, and he would point out a few people to her. She was nervous and came in a wig and dark glasses. Millington got her to remove the glasses. She sat in an upright armchair and twisted her head to look over her shoulder at me, where I stood quietly behind her.
