seven o'clock
It is not quite clear to me how , at present , although I have my idea on the subject . Before I could speak definitely on that point I should like to see the night watchman and the hall porter . '' But neither of these officials was present . They had gone off duty at seven o'clock , and they did not return again till late in the afternoon . It seemed a pity to disturb their rest , but Field decided that they must be sent for -- and indeed he had already dispatched a messenger for that purpose . Till the two men came to the hotel , nothing further could be done in that direction . There was a little pause here .
