‘I’m sorry?’

‘They were called dining clubs,’ he said. ‘Not social clubs. An excuse to go and eat and drink to excess although I daresay we did some charity work and the like.’

Varenka arrived with the tea, Russian style, black with lemon and served in glasses. Once she’d served us she took up a position behind me and Lesley where we couldn’t see her without turning. That’s a bit of a cop trick and we don’t like it when people do it to us.

‘Alas, I am afraid there’s no cake or biscuits in the flat,’ said Woodville-Gentle. ‘I’m not allowed them on doctor’s orders and I’m much more mobile, and ingenious at ferreting out the things that are bad for me than you might think.’

I sipped my tea while Lesley asked some routine questions. Woodville-Gentle remembered the names of some of his contemporaries who he knew had been members of the Little Crocodiles, and others who he thought might have been. Most of the names were already on our list but it’s always good to corroborate your information. He did give us the names of some female undergraduates who he described as ‘affiliate members’ – it was all grist to the mill. Five minutes in, I said that I heard there was a brilliant view from the balcony and asked if I might have a look. Woodville-Gentle told me to help myself, so I got up and, after Varenka had shown me how to open the slide door, stepped outside. I’d absently-mindedly tapped my jacket pocket when getting up. I had a box of matches in there to sell the illusion, so I was pretty certain that they assumed I was going out for a smoke. It was all part of Lesley’s cunning plan.

The view was astonishing. Leaning on the balcony parapet I looked south over the Dome of St Paul’s and across the river to Elephant and Castle where the building affectionately known as the Electric Razor vied for prominence with Stromberg’s infamous poem of concrete and deprivation, Skygarden Tower. And despite the low cloud I could see beyond them the lights of London thinning out as they washed against the North Downs. Turning, I could see right across the jumble of central London to where a trick of the perspective jumbled up the curve of the eye and the spiky gothic shape of the Houses of Parliament. Every high street was bright with Christmas decorations reflected off fresh snow. I could have stood out there for hours except that it was cold enough to freeze my bollocks off and I was supposed to be snooping around.
