four o'clock
I will do my best , for your sake , Mr. Delamere , -- solely for your sake , be it understood , and not for that of the negro , in whom you are entirely deceived . '' `` I shall not examine your motives , Carteret , '' replied the other , `` if you can bring about what I desire . '' `` Whatever is done , '' added Carteret , `` must be done quickly . It is now four o'clock ; no one can answer for what may happen after seven . If he can prove an alibi , there may yet be time to save him . White men might lynch a negro on suspicion ; they would not kill a man who was proven , by the word of white men , to be entirely innocent . '' `` I do not know , '' returned Mr. Delamere , shaking his head sadly .
