The sound of the outboard motor on the boat coming to life can be heard from outside. The motor changes pitch and the sound moves along the wall. I can move the boat from here too. Through a set of patio doors in the corner, the boat glides into view. The phone rings.
Uncle picks it up, listens, then sets it down.
There is a snorkeller missing and sharks reported in the area. Elder grabs his snorkelling gear, walks through the patio doors, and takes off in the boat. Farther ou, Elder passesa mask and snorkel, and begins searching for sharks, but doesn't find any. He deduces that Younger got hit by the boat when Steve moved it. Then looking back the way he came, he sees the sharks.
