It was clear that, despite his conviction that academics preferred to do their own research, Southwell had already dug up everything there was to dig up about Simeon and recorded it in the folder he carried. Madero was tempted but too polite to suggest that a lot of time could be saved if he simply handed it over. Happily after a couple of hours the man’s mobile rang. He listened, then said, “Good lord, is it that time already?”

To Madero he said, “Sorry. Meeting. Lot of nothing, but old Joe Tenderley, our senior partner, tends to get his knickers in a twist. Look, why don’t we meet up later? Better still, have dinner, stay the night. Meanwhile you might care to browse through my notes, see if there are any gaps you’d like me to fill.”

Madero waited till he’d got the folder firmly in his grip before thanking the man profusely but refusing his kind offer on the grounds that he was already engaged in Illthwaite, which if a bed-and-breakfast booking could be called an engagement was true.

Back in his car, he rejoined the tidal bore of traffic, intending to retrace his approach to the town and take the road which Sam Flood had followed some hours earlier around the southern edge of the county, but somehow he found himself swept away toward somewhere called Windermere. He stopped at a roadside inn, brought up a map of Cumbria on his laptop and saw he could get across to the west just as easily this way. Feeling hungry, he entered the pub and ordered a pint of shandy (England’s main contribution to alcoholic refinement, according to his father) and a jumbo haddock. As he waited for his food, he took a long draught of his drink and opened Southwell’s folder.

Out of reach of the solicitor’s voice and with the evidence of the man’s hard work before him, he felt a pang of guilt at his sense of relief at parting company. For every sin there is a fitting penance, that’s what he’d learned at the seminary. It would serve him right if his haddock turned out stale and his chips soggy.
