Kate hears a honking noise and understands that she and Constance are being told in Morse code to go to the tower.

Constance refuses to get out of bed, and Kate considers leaving her. Kate remembers that Mr. Benedict said the success of their mission depended on all four team members, so she forces Constance to get dressed and carries her to the secret entrance.

The entrance is guarded by Martina, who is startled by the girls’ sudden appearance. Kate turns and runs away. Jillson arrives, and Martina suspects that something is going on, so Jillson hurries to find Jackson.

Kate finds a ladder then climbs over the wall on the hill. Jackson runs up to the ladder and starts to climb. Kate fills her bucket with water from the nearby brook and drops it on his head. Jackson falls backward into Jillson and Martina.

Kate makes a lasso with her rope, flings it over the flagpole, ties the end of the rope around Constance’s waist, and climbs up the tower wall. Martina is seconds away from grabbing Constance, so Kate slips the lasso off the end of the flagpole, jumps backward, and acts like a pulley to haul Constance to the top of the tower.
