As with the first two, I didn't write a complete first draft of this one, but I think that's okay, given the complexity of the pattern. As before, I've decided it's sufficient to get at least one stanza to a fairly finished state to show the potential of the form, and then write at least a couple of lines or parts of lines for the remaining stanzas, so at least the framework of the poem is complete.
As before, I'll share the most polished stanza, though it's still far from perfect.
What is that breathing asleep below ground?
A twitching of thought, and a whisker of sound?
A presence below that can never be found?
It is the hare.
