The drone of the pump machinery receded as they walked past the main building and across a small open area. Approaching the administration office and adjacent security station, Summer heard a rustling in some bushes to her left. Recalling the stuffed grizzly bear in the café, she quickly stepped right to veer away from the noise. The confused guard swung his gun hand after Summer while cocking his head toward the bushes. The rustling ceased as the guard stepped closer, then suddenly a figure rose from behind the bushes swinging his arm. The guard spun his gun to fire, but an object whipped out from the prowler’s hand and struck him on the side of the face before he could shoot. Summer turned to see a dive belt, its lead weights strung to the end, clank to the ground. The guard had also dropped hard but managed to stagger to one knee. Stunned and bleeding, he slowly reaimed the pistol at the shadowy figure and squeezed the trigger.

Had the toe of Summer’s foot not struck the guard’s jaw, the bullet might have found its mark. But a hammering kick to his mouth forced the shot high and laid the man out. He slumped over unconscious, the gun slipping out of his hand.

“Those pretty legs are more dangerous than I suspected,” spoke a familiar voice.

Summer looked toward the bushes to see Trevor Miller emerge with a crooked smile. Like Summer, he was clad in a dry suit, and appeared slightly out of breath.

“Trevor,” she stammered, shocked at seeing him there. “Why are you here?”

“Same reason as you. Come on, let’s get out of here.” He picked up the guard’s gun and flung it into the bushes, then grabbed her hand and began running toward the dock. Summer saw a light turn on in the building as she raced to keep up with Trevor.

They didn’t stop until they reached the dock, rushing over to where the security boat was moored. Summer stopped and gazed down at the water as Trevor scooped up the nearby dive gear and tossed it in the boat.

“Dirk went in the water,” Summer panted, pointing toward the gangplank.

“I know,” Trevor replied. He nodded toward the boat, then stepped aside.

Sprawled across the stern bench, dazed and groggy, Dirk stared up at them through glassy eyes. With a laborious effort, he raised his head slightly and winked at his sister. Summer leaped into the boat and collapsed next to him in surprised relief.

“How did you make it out?” she asked, eyeing a trickle of dried blood along his temple.

Dirk weakly raised an arm and pointed at Trevor, who untied the lines and jumped into the boat.
