midnight
When you see me come , do you send round word to the others to meet at midnight on the beach , where you will see the boat drawn up . Can you let your friends know speedily ? '' `` Yes , '' Harry replied . `` My signal was to have been given at daybreak , but I will send round word of the change of hour , and that if , when they are locked up for the night , they see a fire burning on the point agreed , they are to meet on the shore at midnight . Tell William Long to haul the boat up , and let the rowers go to sleep on the shore . We will seize them noiselessly . Then we will row along the shore till off the port , and at first daybreak out to the ship if she be at anchor , or away to meet her if she be not yet come .
