They claimed theft,
but what was stolen?

They could not name it,
but said they felt its loss.

They demanded recompense,
but weren't sure to whom
they should send the bill,
and so they just shouted
the demand out to the universe.

This thing which could not 
be named or described
could be missed;
its loss felt deep within.

They would rage for it
(if in vague terms)
by violent means
if necessary.
