Brixmis was set up after the Second World War to foster good working relations between the occupying forces in the British and Soviet sectors. The French and Americans reached their own agreements with the Russians. For some reason the Brits were allowed as many liaison staff in the Soviet zone as the other two missions combined. Maybe they liked the PG Tips.

Red Ken had served twenty-two years in Para Reg and the SAS, and his face told the whole story – although his roll-up habit must have contributed something to those deep crevasses. He’d spent the last three years driving about in his matt-green Opel, taking pictures of tanks and helping defectors across the wire, but was getting out of the Regiment after this tour. He claimed he had no plans beyond sitting full-time on the terraces at Barnsley FC, but I knew he was talking bollocks.

Tenny was also from D Squadron. He was taking over from Red Ken, but for how long, nobody knew: when the Wall crumbled, so would Brixmis. He was about thirty, very smart and hard. You’d have to be, growing up with a hairdo that looked like a rusty Brillo pad. ‘Tennyson’ wasn’t a name you normally heard shouted across an inner-city playground, but his drop-dead gorgeous fiancee seemed to like it, and I guess that was all that mattered.

Tenny had always been a star. After university and a spell in the OTC, he decided he wanted to hang out with squaddie lowlife rather than do what he should have done – become a doctor or lawyer or something that lined his pocket. Tenny had been going places. He had golden balls. We all knew he was destined for better things. For me, being in the Regiment was the best I was ever going to get. For him, it was just another stepping-stone to global domination.
