About nine o'clock
I 'll just tell you a little thing and you can form your own conclusions . Last night we was open late at the ` Black Post . ' We keep open , sir , as you know , when you gentlemen at the Stock Exchange are busy . About nine o'clock there was a strange customer came in . He had two drinks and he sat as though he were waiting . In about ` arf-an-hour another gent came in , and they went into a corner together and seemed to be doing some sort of business . Anyways , there was papers passed between them .
