"They may have been false," suggested the sergeant. "You've got false ones on." "And they still itch terribly." "Why don't you take them off?" inquired Mr. Cook. "I guess you won't need them any more to-night, will you?" "That depends on what is going to happen," said Bob. "Have you any plans, Sergeant?" "I wish I had," exclaimed Riley. "What I want to find out is where this gang has its headquarters. When I know that I'll go there and pay a call." "I know where it is," said Bob. "You do?" demanded the sergeant in surprise. "What are you two anyway; a couple of young Sherlock Holmes?" "Not at all," laughed Bob. "We are suspicious of a certain house though, and it might be worth while to go up there and take a look around." "That's the stuff," exclaimed Riley eagerly. "I'll swear you all in as deputy sheriffs, and we'll get guns for yez and go up just as soon as we can." "We're only suspicious of this house, you know," said Bob. "Where is it?" "Twelve eighty-two Elm Street." "I heard Heinrich say something about Elm Street," exclaimed Riley. "Your clue may be a good one after all." "Poor old Heinie," murmured Bob. "Poor old nothing," cried Riley. "Who feels sorry for a German plotter?" "But Heinie was stupid and they probably made a fool of him." "The fact remains, however, Bob," said Mr. Cook, "that Heinrich evidently was in with this gang and therefore he ought to be punished." "You're dead right, Mr. Cook," exclaimed the sergeant. "No matter whether a man's been made a fool of or not, if he's dangerous he ought to be locked up." "I suppose so," Bob agreed. "I feel sorry for him though, more sorry than I do for Lena. She has more brains than Heinie and ought to know better." "Meanwhile we ought to be on our way to Elm Street," exclaimed Sergeant Riley. "Come on, boys, let's get started." CHAPTER XXVII A RAID AND A SURPRISE Mr. Cook's automobile was still standing outside, and a few moments later the little party of four were seated in it and on their way to the police station. Bob was at the wheel. Upon their arrival it was the work of only a few moments to have Mr. Cook and the two boys sworn in as deputy sheriffs. Bob and Hugh retired to the wash room and after more or less trouble succeeded in removing the false crop of hair from their faces. Sergeant Riley ordered two policemen in uniform to go with them, and when Mr. Cook, Bob and Hugh had been equipped with pistols and heavy night sticks, the band, now increased to six, were ready to proceed. They used the Cooks' car again and presently were gliding silently along in the direction of Elm Street.
