Soon after that the wagon drove up before the dingy headquarters. The prisoners were jerked from the wagon rather than lifted out, and were dragged into the building, up a pair of stone steps and along a dimly lighted corridor.
Arriving in front of a grated door, the policemen in charge of the boys waited until an attendant had unlocked and opened it, whereupon they threw the Battleship Boys inside.
The door shut with a loud clang, and the gendarmes marched away, down the corridor without a word to their prisoners.
For a moment the boys lay where they had been thrown. Then Dan sprang to his feet, and, going to the door, peered out into the corridor. All he could see was a brick wall in front of him.
Sam sat up, rubbing his red head reflectively.
"I wonder where we are?" muttered Dan.
"Where we are?" repeated Sam.
"Yes."
"Don't you know?"
"I do not."
