The current dragged them down through the warm darkness. They had no lights, but were not drifting blindly. Sophisticated sensors were pointing them towards the chemical trail leaking from their target.
Something large swept through their group, taking many of them with it. They had no warning and no defence to its sudden attack, yet they continued on without fear. They were all expendable, but that did not mean they were suicidal, and the longer they stayed in the open the greater their losses. Reaching the target was their only hope of survival.
As the signal strengthened, a predator smashed through their ranks again. Those remaining made it to the wall and locked themselves into position. The river continued to roar past, but they were safe now. The wall was quickly breached and they poured inside. They released their chemical weapons and DNA fragmented beneath their onslaught. From this first infected cell they had gained a base for viral replication, safely away from the white blood cells.
Jenny sneezed and reached for a tissue.
‘Bless you,’ a passing stranger said with a smile.
‘Thanks,’ she said, returning the smile. ‘Must be something in the air tonight.’
