There wasn't time to think about it. He set her down and returned his attention to the orcas. They were milling around the rowing boat and the girl's gun was lying amongst the rocks. He ran down, retrieved it from the water, and threw it to her.
She fired a bust and the orcas scattered.
'Professor. Get into the boat. I'll take you to safety.'
Another burst followed and Tom jumped into the boat. He watched as the girl ripped off the bottom of her suit and hobbled, naked, towards him. She was cut and bruised and had difficulty making her way amongst the rocks. That gave the orcas a chance to move in. They fastened their teeth on the tow ropes and dragged him out to sea.
