Ours was a family with a habit for nicknames, which meant it was also a family of disguises.

The arrangement appeared strange, but life still was haphazard and confusing during that period after the war; so what had been suggested did not feel unusual. We accepted the decision, as children do, and The Moth, who had recently become our third-floor lodger, a humble man, large but moth- like in his shy movements, was to be the solution. Our parents must have assumed he was reliable. As to whether The Moth’s criminality was evident to them, we were not sure.

I suppose there had once been an attempt to make us a tightly knit family. Now and then my father let me accompany him to the Unilever offices, which were deserted during weekends and bank holidays, and while he was busy I’d wander through what seemed an abandoned world on the twelfth floor of the building. I discovered all the office drawers were locked. There was nothing in the wastepaper baskets, no pictures on the walls, although one wall in his office held a large relief map depicting the company’s foreign locations: Mombasa, the Cocos Islands, Indonesia. And nearer to home, Trieste, Heliopolis, Benghazi, Alexandria, cities that cordoned off the Mediterranean, locations I assumed were under my father’s authority. Here was where they booked holds on the hundreds of ships that travelled back and forth to the East. The lights on the map that identified those cities and ports were unlit during the weekends, in darkness much like those far outposts.

At the last moment it was decided our mother would remain behind for the final weeks of the summer to oversee the arrangements for the lodger’s care over us, and ready us for our new boarding schools. On the Saturday before he flew alone towards that distant world, I accompanied my father once more to the office near Curzon Street. He had suggested a long walk, since, he said, for the next few days his body would be humbled on a plane. So we caught a bus to the Natural History Museum, then walked up through Hyde Park into Mayfair. He was unusually eager and cheerful, singing the lines Homespun collars, homespun hearts, Wear to rags in foreign parts, repeating them again and again, almost jauntily, as if this was an essential rule. What did it mean? I wondered. I remember we needed several keys to get into the building where the office he worked in took up that whole top floor. I stood in front of the large map, still unlit, memorising the cities that he would fly over during the next few nights.
