March 20, 1913. 10:45 p.m. Shanghai North Station. A man had just shaken hands with the friends who came to see him off. He was still talking when a shot was fired. Song Jiaoren was 31. Weeks earlier he had led his party to victory in the first nationwide election in Chinese history. He was on his way to Beijing to form a cabinet. He never arrived. This episode reconstructs the scene hour by hour, and then does something most accounts refuse to do: it measures the suspects and admits where the evidence stops. WHAT THIS EPISODE COVERS - The station: British-designed, four storeys, built for 329,000 silver dollars, and the exact minute the shot was fired - The seventeen hours: two German doctors, a poisoned bullet, and the three things he asked his comrades to do - The telegram: Song's last message to Yuan Shikai, read in full, including the two lines that are still the hardest to answer - The first national election: 42.93 million voters, 870 seats, and who was actually allowed to cast a ballot - The chain of the case: four layers, from the cabinet in Beijing to a gunman on a railway platform - The four measures: motive, means, timing, gain, measured one by one, on every candidate - The tomb: two characters cut in stone, a tablet pushed into a pond in 1966, and what "waiting for an honest historian" means THE FOUR MEASURES Motive: who became worse off the moment Song was about to form a cabinet. Means: who needed a gun, and who only needed to withhold a nod. Timing: who could have stopped him, and did not. Gain: who collected, and who paid. We put the four columns side by side and leave the last cell empty. This film names no one. The verdict is yours. PASSAGES MARKED AS INFERENCE Where the record ends, we say so. Every counterfactual passage in this episode is introduced on screen as inference, not record, including the ones that would have saved his life: a plain-clothes officer on the platform, two attendants walking ahead, a newspaper printing the rumour one day earlier. All three were possible at the time. None of them happened. SOURCES AND METHOD Dates, figures, telegrams and edict texts in this episode follow the published records: the electoral law and results of 1912 to 1913, the Shanghai press of March 1913, the Mixed Court proceedings, the abdication edict of February 12, 1912, and the inscriptions on the Song Jiaoren tomb in Zhabei Park, Shanghai. Where later writers disagree, the episode says so and identifies the disagreement as a school of opinion rather than a finding. VISIT THE PLACES Shanghai Railway Museum, the 1909 station building, still standing. Song Jiaoren's tomb in the northwest corner of Zhabei Park, with the eagle on top and the stone tablet bearing two characters: the Fisherman.
