A deux heures du matin, Drebber était trouvé mort dans la maison de Brixton Road : le point important était donc de connaître l’emploi du temps de Stangerson entre huit heures et demie et l’heure du crime et de savoir ensuite ce qu’il était devenu.
At two in the morning Drebber had been found in the Brixton Road. The question which confronted me was to find out how Stangerson had been employed between 8.30 and the time of the crime, and what had become of him afterwards.
