Mac let its side swipe him again to get a feel for just how big. The salt water stung his eyes but he could clearly see the grey shape circling him. At least it wanted him and not Mandy. He waited until the beast circled back and punched it hard in the snout. It shook its head but came around again quickly for an attack this time. A tiger shark—alone, he hoped. Mac hit it with his knife on the left and struck out again with his knife under its belly before it could swim away. The wound would bleed and that meant he had to get Mandy away from the tainted water before the sharks near the two crash sites got wind of the fresh blood. The shark circled back around fast. Mac brought his knife down with both hands, nearly losing the blade when the beast swung away. Thank fuck it had decided they were too much trouble because he knew Mandy was panicking. Surfacing, he was met with a scream of his name and Mandy jumping on him in relief and dunking him under again. Any other time he’d be happy she seemed to be unable to keep her hands off him.
