Christina Rossetti's speaker refuses to tell a secret, and the refusal takes up the whole poem. Nothing is confessed, and by the end we may not even know there is anything to confess. That is the trick. "Winter: My Secret" is a performance of privacy, half teasing and half serious, in which the weather becomes an excuse, a disguise and finally a metaphor for guardedness.
The opening line sounds like a flat refusal: "I tell my secret? No indeed, not I." Almost at once the speaker wobbles: "Perhaps some day, who knows?" The poem is full of this kind of flirtatious back-and-forth. She scolds the listener for being "too curious: fie!", then offers "You want to hear it? well:" and slams the door again with "my secret's mine, and I won't tell." In the second stanza she doubts the secret exists at all: "Suppose there is no secret after all, / But only just my fun." This twist matters. The secret may be a game, or the secret may be that there is no secret, and the speaker enjoys keeping us guessing either way.
Winter gives her the perfect cover, and the imagery of cold is where the writing is most inventive. The day is "nipping" and "biting", so she needs "a shawl, / A veil, a cloak, and other wraps." These are practical garments, but they work as emotional ones too. She will not "ope to every one who taps", as if the listener were a visitor knocking at a house, and the draughts that "come whistling thro' my hall" stand for unwanted intrusion. Then the sound takes over. "Come bounding and surrounding me, / Come buffeting, astounding me, / Nipping and clipping thro' my wraps and all": the repeated "Come" and the clustered rhymes make the wind sound like a pack of playful, pestering animals. The comedy sharpens when she asks who would "show / His nose to Russian snows / To be pecked at by every wind that blows?" The wind becomes a bird, and the sharp little words "nose", "snows", "blows" snap together like beaks.
The form suits all this wavering. Line lengths jump between short exclamations ("And you're too curious: fie!") and long, breathless runs. The first line is a steady ten syllables, but the poem quickly loosens. Rhymes arrive in unpredictable patterns, and sometimes they cluster, as in "froze, and blows, and snows" in the first stanza. The effect is of a voice thinking aloud, changing its mind, and enjoying its own cleverness. Even the apology to the listener ("You would not peck? I thank you for good will") is polite and evasive at once, because she accepts the kindness and then asks to "leave that truth untested still."
In the final stanza the poem moves through the seasons, and each one is judged unsafe. Spring is "expansive", yet March has its "peck of dust", April its "brief showers", and May's flowers can be withered by "One frost." The speaker will trust none of them. Only a "languid summer day" might do, and she hedges even that with conditions: "not too much sun nor too much cloud", wind "neither still nor loud". The balance is so exact that it may never arrive, which would postpone the secret for good. The poem ends on two short, offhand words: "Or you may guess." The listener is handed the job of imagining, and perhaps that is the point.
What makes the poem worth reading is that it hides so openly. Readers may be tempted to hunt for the real secret, but the poem seems designed to frustrate that hunt, so the interest lies in the manner of concealing. It treats reticence as something lively, with wit, rhythm and a good deal of mischief in it. Yet beneath the play there is a serious sense that inner life needs shelter, and that letting people in should wait for the right moment.
