Dave Bonta's poem is only a few lines long, but it packs in a strange tension. The speaker watches a prison guard, or perhaps listens to him, as he talks about release. That should be good news. Yet the guard is described in unsettling ways: "an epicure of secrets," someone who savors what he knows the way a gourmet savors food, and "an unsafe door," a gate that ought to be secure but somehow isn't.
The final image is the most striking. The guard is "a messenger from their last / day in the world." The word "their" suggests the prisoners, and the line hints that release may mean something final, even death, or at least the end of the life they knew. Judging by the imagery, the speaker feels uneasy and wary, unable to trust the person who holds the keys. The mood is quiet, tense, and ambiguous, with hope and dread tangled together in a single word.
