For a couple of seconds, I bucked and danced at the end of my line. I was like a rag doll shaken by a giant.
Was it a great white shark, twisting and turning me from side to side, like a bulldog with a rat in its jaws?
I couldn't see what was happening. It was dark, and air bubbles kept exploding around my face mask.
Don't panic! I told myself. Don't panic!
I tried to think it through. I didn't feel razor-sharp teeth cutting through my wet suit. So it wasn't a shark.
Don't panic. Don't panic.
