Chapter 25: The Clockwork Widow

The third chess player was completed in the autumn of the following year. Van Cleef sent a note: *It plays at seven levels. The seventh level is unbeatable. Levels one through six are calibrated to teach rather than defeat. I have tested it against forty-seven opponents of varying skill. The learning effect is measurable.* A postscript: *She would have adjusted the fourth level. I've left a note in the instruction mechanism describing the adjustment, for whoever next works on it.* Crane went to Rotterdam to see it. The third chess player sat on a bench in the workshop's front room, finished and operational, with a quality that the first two also had — a presence that was hard to attribute to mechanism alone and that Crane had stopped trying to explain through purely mechanical terms. It had the quality of something that had been made with intention. He played it at level three. He lost in eleven moves, in a manner that made clear that he had made a fundamental error at move five and the subsequent six moves had been the natural consequence of not recognizing it. The loss was instructive. 'She built it to teach,' Van Cleef said. 'Everything she built was to teach something. The diagnostic automaton teaches engineers what to look for. The second chess player carries the knowledge forward. This one creates the conditions for learning in the first place.' Crane thought about Mrs. Farquhar. He had never met her. He knew her better, he suspected, than most people who had. 'What do you know about the widow in the official case description?' he asked Van Cleef. 'The one the coroner described as a natural death.' 'She was not a widow,' Van Cleef said. 'Her husband was still living — estranged, in Scotland, which the papers had recorded as deceased for simplicity. She had arranged the simplification herself, years ago, for reasons I don't fully understand.' 'For independence,' Crane said. 'A widow in this period has more legal standing than a separated wife. She arranged her own status.' Van Cleef looked at him. 'I didn't know that,' he said. 'I found the marriage record in the Leeds registry in the second week,' Crane said. 'I noted it and filed it as personal history not directly relevant to the case.' He looked at the chess player. 'It is relevant to understanding her. She had been arranging her own circumstances to suit her purposes for decades. The evidence chain, the hidden documents, the chess player — none of that was improvisation. She had been building that kind of infrastructure her whole life.' Van Cleef was quiet for a moment. 'The clockwork widow,' he said. 'The coroner's description.' Crane looked at the third chess player, which was watching them both with the specific quality of attention that her mechanisms had. 'Not accurate. She was the clockwork architect. The widow status was one of her mechanisms. The clocks were another. The chess player was another. She built systems to protect what she cared about.' 'And she built you into the system,' Van Cleef said. 'Without knowing you.' 'She built a mechanism that would find the right person,' Crane said. 'She trusted the mechanism.' 'Did the mechanism work?' Crane thought about Harwick's sentence, the Society's reorganization, the parliamentary committee recommendation, the diagnostic automaton in commercial production under the Society's patent, the third chess player calibrated to teach seven levels of chess to anyone who could afford the modest rental the Society charged, which was set at the cost of the mechanism's maintenance rather than its commercial value. 'The mechanism worked,' he said. He played the chess player at level four on his way out. He lost in sixteen moves. He understood, by the end of it, what he had done wrong at move nine. He made a note. On the train back to London, with Kepler presumably reorganizing something in his absence, he thought about a woman who had understood that the best way to protect something was to build a system that could protect it without her. Who had built that system with the same precision she brought to everything else. Who had taught him, posthumously, more about the nature of evidence than any case he had worked before. The Society was intact. The work continued. The third chess player was teaching level-one students in the Society's new education program. Inspector Osei had three cases on her desk that used the evidentiary framework the parliamentary committee had adopted. Documentation outlasted people. Ideas outlasted documentation. She had been right.
