ten o'clock in the morning
Set to work . I shall only keep this end of the scarf . If ever you want to piece the scarf together , bring me the other end , the one which the police will find round the victim 's neck . Bring it me in four weeks from now to the day , that is to say , on the 29th of December , at ten o'clock in the morning . You can be sure of finding me here . And do n't be afraid : this is all perfectly serious , friend of my youth ; I swear it is . No humbug , honour bright .
