midnight
Paul had slept well and was rested , so Henry leaned over and shook him . Paul opened his eyes , and any question that he might have wished to ask was cut short at his lips by Henry 's low , but commanding , `` Caution ! Caution ! '' `` It is far after midnight , and we must move , Paul , '' said Henry . `` They may have blundered on our trail before it was dark , and they are still looking for us . I think they are coming this way . '' Paul understood in a moment , but he asked no question ; if Henry said so , it was true , it did not matter how he knew .
