“The Seventh Street Bridge will be blasted at one o’clock,” Penny said anxiously. “If it goes up, Riverview traffic will be paralyzed. Work at the munition plant will stop cold.”
“The saboteurs intend to blame Burt Ottman for the job too! Well, at least we can tell police who the real plotters are.”
“We can if we ever get out of here,” Penny said, pacing the floor. “Oh, I’m as mad as a hornet!”
“Quiet down, and maybe we can hear something,” Louise suggested calmly. “I think those men are talking.”
A murmur of voices could be heard from the third floor of the ark. The partitions were thin. By standing on one of the pigeon boxes, the girls discovered they could understand nearly everything that was being said.
“Carl, you go back to the shack and keep an eye on Ottman,” the waiter ordered the watchman. “As soon as Breneham comes, send him here. We’ll pull the job at one o’clock just as we planned.”
“Okay, Jard,” the other answered.
Getting down from the pigeon box, Penny watched Carl Oaks leave the ark.
“How about taking a chance and shouting for help?” Louise suggested in a whisper.
Penny shook her head. “Not now at least. I doubt anyone is within a mile of this place—that is, anyone friendly to us.”
