An unobtrusive man, he was noticed by few of the pedestrians who shared the steps with him that climbed to the pavements of Vauxhall Bridge in the November rain. He left behind him the cream and green walls and the darkened plate glass expanses of the building that those outside the disciplines of the Service called ‘Ceausescu Towers’ – the headquarters of MI6. He walked briskly. It was his job to move unseen and not to attract attention, even inside the Towers. Len Gibbons was known to few of those who passed through the security gates, morning and evening, alongside him, or shared the lift to and from the third floor where his desk, East 3-97/14, stood, or waited in the canteen lunch queue with him. The few who did know him, however, regarded this middle-grade manager as a ‘safe pair of hands’ and in the trade that was about as good an accolade as could be handed out. As a ‘safe pair of hands’, he was entitled to trust and responsibility and he had received both that afternoon at a meeting with the director general: no notes taken.

The word of the day was deniable. The meeting in itself was deniable, the matter discussed was deniable, and the conclusions reached were deniable. The actions that would be taken were also deniable. Len Gibbons had been called to the upper floors and briefed over a pot of tea and a shortbread biscuit. Take the bastard down, Len, would be the vulgar way to put it. Take him down and leave him on a kerb so that his head rolls in the gutter and the blood runs down the drain. Not, of course, that we like vulgarity. We might more politely call it ‘interdiction’. Actually, I prefer ‘take the bastard down’. It’ll be deniable. My diary has me in the Cabinet Office fifteen minutes ago, and there all afternoon. So, go to it, Len, and know that many men – and widows – will be cheering you on. If you bring him down there will be cheering to the rafters. It’s not the sort of thing we’ve done in years – a first in my time – but it has my total support… as long as it stays deniable.
