‘I don’t understand.’ Fabel reached out his hand, slowly. ‘Give me the rifle, Georg. You can explain it to me. We can talk about it. We can sort things out.’

‘Sort things out?’ Aichinger smiled a sad smile. It struck Fabel that there was a genuine but sorrowful gratitude in that smile. Aichinger’s posture seemed to relax. The thumb on the trigger stopped quivering. ‘I’m glad it was you, Herr Fabel. I know that when you think about what I’ve said, you’ll understand it. At least you do something. At least there’s some sense, some meaning, to each day that you wake up to. You save people. Protect them. I’m glad it was you who I could explain to. Tell everyone … tell them that I couldn’t live with being someone else. Tell them I’m sorry.’

The sound of the shot was muffled by the flesh pressed hard against the barrel under Aichinger’s jaw. There was a plume of blood, bone fragments and brain matter from the crown of Aichinger’s head and his legs folded beneath him.

Fabel leapt across the body and ran into the living room. Towards the tiny feet in the doorway.

Ansgar’s meal was ready.

Ansgar Hoeffer’s home in Cologne’s Nippes district was modest and scrupulously clean and tidy. It was also unshared, unvisited. Over the years he had gradually withdrawn to specific places: home, work, the journey in between. He often felt that his life was like a large country house in which only a few rooms were used and kept in perfect order, the rest closed and shuttered and dust-sheeted in the dark. Rooms, Ansgar knew, it was best not to visit.

The kitchen of Ansgar’s home was, given his occupation, surprisingly small but unsurprisingly well equipped; pristine and filled with light from the large window that looked out onto his house’s slim fringe of garden and the blank side wall of his neighbour’s house.

The oven chimed. The meat was ready.

The strange thing was that, when at home, Ansgar preferred to cook simpler meals. Uncomplicated dishes in which the true texture and flavour of the meat were allowed honest expression. As always, Ansgar had timed everything to perfection. The asparagus simmering on the hob would be cooked to the perfect consistency. He took the small dish of apple sauce from the fridge: it would reach the perfect temperature – cool but not chill – by the time he served the meat and asparagus. He poured half a bottle of Gaffel beer into a glass, the balance of body and foamy head exactly right. He removed the metal tray from the oven and unwrapped the single fillet of meat from its foil cocoon. Leaning forward, he sniffed the delicate scent of the tender flesh wrapped in thyme, his glasses steaming opaque for a second. He placed the meat on the plate, dressed it with a fresh sprig of thyme and some of the apple sauce. He drained the asparagus and laid it neatly beside the meat.
