The Briton was too strong for him, and in one convulsive heave he turned over on top of Cato, facing up to the morning sky and pressing back on the body trapped beneath him. The impact drove the breath out of Cato, and he just had the sense to clamp his lips shut before the water closed over his face. But he knew he had little time left. His burning lungs demanded air, and he would be forced to release his grip on the rider and try to force his way to the surface. Out of the corner of his eye something glimmered. The sword. Cato twisted his head and saw that it was within easy reach on the bed of the stream. He released his grip on the man’s throat and snatched at his face with his left hand, fingers working towards the man’s eyes. His right hand splashed back into the water, grabbed for the handle of the sword, brought the blade round, and then with the last of his fast-ebbing strength he thrust the blade up through the rider’s back. The man jerked, in spasm, jerked again, frantically struggling to tear himself free of the blade, which Cato was working furiously up and down in his chest. The thrashing became weaker, and at last Cato heaved the body to one side and burst out of the stream, gasping for air. As he sat coughing and spluttering in the slowly spreading pool of crimson, Cato checked his enemy. The rider lay on his back. The tip of Cato’s sword had burst through his heart and right through the front of his chest. Dark red billowed up round the edge of the blade and slowly dissipated in the gentle current. The man’s head was tilted back beneath the surface of the water. His eyes stared sightlessly at the sky as his hair waved downstream, like the long tendrils of the weeds growing close to the bank.
