Aline Kilmer knew something about the difference between public composure and private feeling. Born in 1888, she married the poet Joyce Kilmer, and when he was killed in the First World War in 1918, she became a young widow with children to raise. Her short lyric “To an Intruder” appeared in the collection *Candles That Burn* in 1919, in the immediate shadow of that loss. The poem can be read as more than a war widow’s lament, though: it is a compact defense of anyone whose inner life is not open to casual visitors.
The speaker addresses someone who has mistaken her reserve for emptiness or invitation. She admits that she wears “a guarded face / To all the world but one or two,” and that in her “heart’s most secret place” she contemplates lilies. The intruder, by contrast, has roses that “grow in common ground.” The central idea is not simply that people are different; it is that some kinds of beauty and sorrow are sacred, private, and vulnerable, while others are ordinary and easily shared. The speaker’s lilies need the protection of a cloister, and the intruder’s roses belong to the open garden. To force entry into her hidden place is an act of desecration, which the closing question makes plain: “why should you / Whose roses grow in common ground / Profane the cloister I have found?”
Kilmer builds that argument through a single six-line question. The meter is mostly iambic tetrameter, a steady four-beat line that feels calm and controlled on the surface, much like the guarded face itself. The rhyme scheme, ABABCC, starts with alternating rhymes that open the poem outward and then tightens into the couplet “ground” and “found.” That final rhyme locks the door, so to speak, after the central contrast has been drawn. The enjambment across lines three and four also matters: the speaker is quietly “in” her secret place considering lilies when the abrupt “why should you” cuts across the line. The syntax therefore performs the intrusion the speaker is resisting.
The imagery is deliberately small but sharply divided. “Guarded face,” “secret place,” and “cloister” all suggest enclosure, watchfulness, and things set apart. “Lilies” carry biblical weight: “Consider the lilies of the field” points toward a spiritual attention that asks for trust rather than display. In Kilmer’s hands, lilies are not merely flowers; they are emblems of a private grief or devotion that cannot be marketed or explained. “Roses” and “common ground” sit on the other side of the line, representing a beauty that is real but public, conventional, available to everyone. The word “profane” is the sharpest in the poem. It turns the speaker’s inner world into a holy place and the intruder’s curiosity into a kind of trespass.
What makes the poem significant is how much it claims in such a small space. Kilmer refuses to perform her sorrow for an audience. In a time when women’s grief was often expected to be visible and decorous, she insists on a hidden sanctuary that owes nothing to public expectation. The poem also speaks beyond its moment: to introverts, to mourners, to anyone whose deepest self is not a common rose garden. Its brevity is part of its argument. It gives the reader only a glimpse of the cloister, not an open gate, and that restraint is exactly what the speaker is defending.
