Shadows at noon
Take a deep breath
Dive back in
Pull together
Dislodging derelict in the depths
Lies beneath the city
Safe falling and hard landings
Something’s not right down here
Unearthing secrets
They never made it to market
Skipping stones at the beach
Hanging up
Do an elevator pitch
It comes together
