Eleven. Twelve. Thirteen. Fourteen. Fifteen…
Slide arm under neck, tilt head back, pinch nose, breathe into mouth.
Repeat.
Push down hard on centre chest… One. Two. Three. Four…
Come on, Sherlock…
Thirteen. Fourteen. Fifteen!
Bend down… hand under neck again, tilt to stretch out airway, pinch nose, blow into mouth… twice.
Repeat.
Slam both hands down hard to compress heart and lungs back into motion… One. Two. Three. Four…
"Breathe Sherlock!"
Thirteen. Fourteen. Fifteen…
Crouch back down… tilt neck up, pinch nose, take deep breath, exhale past cold lips.
"It's been almost 2 minutes, John."
Blow again, pushing harder, willing the breath to catch hold…
"Shut up, Lestrade!"
One. Two. Three. Four. Five… Damn it!
Desperate shake to the shoulders… Fearful slap on that sharp, ashen cheekbone.
"SHERLOCK!"
Grey eyes fly open. Slow few seconds of recognition, discovery, pain… a wracking, shuddering spasm overtakes the limp body.
John helps him roll to his side, as at least a pint of water comes spattering out.
"What were you thinking, Sherlock!"
More sputters and gasps…
"I had to save her."
"But, you don't know how to swim!"
"Yes…. (cough)… well… (sniff)… I didn't know the current would seize with such force…"
"Bloody hell, Sherlock… you scared us all…"
"Fine. It was… unwise."
"I was going to say barmy, but I'll settle on brave."
