midnight before
There was something of a running fight , and quite a few shots were exchanged . In this fight two of the Germans were seriously wounded , and one of the Secret Service men got a bullet through his shoulder . But in the end all of the enemy were captured , and then the authorities took charge of the disabled submarine , and also the underground workshop , where the Germans had been laboring so hard to get their undersea boat once more into shape to sail . It was after midnight before all these happenings came to an end and the evildoers had either been placed in jail or under a strong military guard . The capture , of course , was kept as secret as possible by the government officials . `` And to think that the fathers of Nappy Martell and Slugger Brown are guilty ! '' cried Ruth Stevenson , when Jack met her later on and told her some of the particulars .
