The policeman, Geordie Keating, says on meeting Sidney Chambers for the second time that England lost to Hungary 6-3 the previous evening. He is referring to the international football match on the 25th November 1953, allowing the events here to be dated to 26th November.
Just before handing over the diary he has just taken from the widow to the policeman, Sidney Chambers says "I have just broken the eighth commandment." The eighth commandment is "Thou shalt not steal."
