‘A colleague of my husband’s. A lawyer named John Squales. My husband hadn’t met him, but their two firms were…’ She gestured vaguely.

‘Affiliated?’

‘Yes, I suppose. When Mr. Squales found out we were going to be in London on vacation, he invited us to his home for dinner. Lonnie had always written him at his office, of course, but he had Mr. Squales’s home address on a slip of paper. After we got in the cab, he discovered he’d lost it. And all he could remember was that it was in Crouch End.’ She looked at them solemnly.

‘Crouch End – I think that’s an ugly name.’

Vetter said, ‘So what did you do then?’

She began to talk. By the time she’d finished, her first cup of coffee and most of another were gone, and PC Vetter had filled up several pages of his notebook with his blocky, sprawling script.

Lonnie Freeman was a big man, and hunched forward in the roomy back seat of the black cab so he could talk to the driver, he looked to her amazingly as he had when she’d first seen him at a college basketball game in their senior year – sitting on the bench, his knees somewhere up around his ears, his hands on their big wrists dangling between his legs. Only then he had been wearing basketball shorts and a towel slung around his neck, and now he was in a suit and tie. He had never gotten in many games, she remembered fondly, because he just wasn’t that good. And he lost addresses.

The cabby listened indulgently to the tale of the lost address. He was an elderly man impeccably turned out in a gray summer-weight suit, the antithesis of the slouching New York cabdriver. Only the checked wool cap on the driver’s head clashed, but it was an agreeable clash; it lent him a touch of rakish charm. Outside, the traffic flowed endlessly past on Haymarket; the theater nearby announced that The Phantom of the Opera was continuing its apparently endless run.

‘Well, I tell you what, guv,’ the cabby said.
