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