Sam Fisher- Floor into Canal

  Even before Fisher shifted his weight to his forward foot, he knew something was wrong, could feel the sole of his boot sliding sideways on the spot of grease or rainwater or whatever it was on the concrete. Before he could react, he was falling through space. The floor loomed before him. At the last moment he reached out and smacked his palm against a section of pipe. He twisted sideways, slowed ever so slightly; then his body was horizontal and falling again. He curled himself in a ball, arms wrapped around his head, legs tucked to his chest.

  The loam softened the impact, but he still felt as if he'd taken a body blow from a heavyweight boxer. Swirling sparks burst behind his eyes.

  He heard a crack, then a pop, then silence.

  The floor splintered beneath him; then he was falling again.
...

  HAVING punched a ragged, man-sized hole through the floor, Fisher found himself falling amid a cloud of dust and ash that obscured his vision save for a few jumbled glimpses of concrete, steel pipes, and moonlight glinting off water. Water. The canal. With no way of knowing how deep it was, he scrambled to right himself, twisting his torso and flailing his arms until his internal gyroscope told him he was right side up. He spread his limbs like a parachutist, sucked in a breath, and set his jaw.

  The impact felt like someone had slapped him in the sternum with a twelve-inch plank. His world went dark and quiet. Despite being shielded from the sun, the water was surprisingly warm. His head broke the surface. He checked his waistband: The SC pistol was still there. He checked his wrist: The OPSAT was gone.
