The miniature battle of Shanghai had been swept aside. Broken soldiers lay scattered among my train set and model cars. Someone, perhaps Coolie or Number 2 Boy, had used my Robinson Crusoe as an ashtray, stubbing his half-smoked cigarettes into the cover as he watched nervously from the windows. I thought of reporting him to my father, but I knew that the servants had been as frightened as I was.

I gathered the soldiers together and later tried to play with them, but the games seemed more serious than those that had filled the playroom floor before Bloody Saturday. When David and I set out our rival armies it worried me that we were secretly trying to kill each other. Thinking of the severed hands and feet I had seen outside the Amusement Park, I put the soldiers away in their box.

But at Christmas there were new sets of soldiers to take their place, Seaforth Highlanders in khaki battle kilts and Coldstream Guards in bearskins. To my surprise, life in the International Settlement was unaffected by the months of fighting around the city, as if the bitter warfare had been little more than a peripheral entertainment of a particularly brutal kind, like the public strangulations in the Old City. The neon signs shone ever more brightly over Shanghai’s four hundred nightclubs. My father played cricket at the country club, while my mother organised her bridge and dinner parties. I served as a page at a lavish wedding at the French Club. The Bund was crowded with trading vessels and sampans loaded with miles of brightly patterned calico which my father’s printing and finishing works produced for the elegant Chinese women who thronged the Settlement. The great import-export houses of the Szechuan Road were busier than before. The radio stations broadcast their American adventure serials, the bars and dance halls were filled with Number 2 and Number 3 girls, and the British garrison staged its Military Tattoo. Even the Hell Drivers returned from Manila to crash their cars. While the distant war between Japan and Chiang Kai-shek continued in the hinterland of China the roulette wheels turned in the casinos, spinning their dreams of old Shanghai.

As if to remind themselves of the war, one Sunday afternoon my parents and their friends drove out to tour the battlegrounds in the countryside to the west of Shanghai. We had attended a reception given by the British Consul General, and the wives wore their best silk gowns, the husbands their smartest grey suits and Panamas. When our convoy of cars stopped at the Keswick Road checkpoint I was waiting for the shabby Japanese soldiers to turn us back, but they beckoned us through without comment, as if we were worth scarcely a glance.
