January sets up the joke by introducing the sceptic. Patience Scalpel, an invented character, belongs to the almanac for one reason: she cannot understand what the women around her see in each other. She asks the question repeatedly and never gets an answer she accepts, and she is the only voice in the book that speaks for ordinary marriage and children.
February is a single unbroken love letter, addressed to a woman who has been loved by everyone already, worrying that there is no new way left to do it. "Saints Days" then canonises Dame Evangeline Musset, the book's heroine, with one entry per month of her life: what she managed at five, at nine, at fifteen, at twenty-one, at thirty, at fifty, at eighty-eight.
March brings two Englishwomen to Musset's tea table. Lady Buck-and-Balk wears a monocle and believes in spirits; Tilly-Tweed-In-Blood wears a Stetson and believes in marriage, and wants the House of Lords to legalise weddings between women so that alimony can be collected when one of them strays. Musset suggests duelling instead. They are joined by Masie Tuck-and-Frill, a midwife who has run out of work and still checks hopefully between the sheets, and by Patience Scalpel, who arrives, throws off her furs and asks whether there is a man about the place.
The middle months work as an almanac proper. April lists the symptoms of the condition, from the giggling of the early stages to the acute melancholy of the advanced. June is a poem of portents. July reproduces the letters women in love write to each other and then despairs of them. August catalogues the distempers, including the woman who cannot stop telling the neighbourhood what she did last night. September argues that jealousy between women has no excuse to hide behind, since no question of a child's paternity arises, and is therefore more honest and no less painful.
October is the book's one sustained portrait of an unwanted admirer: Daisy Downpour, a corset-maker, who stands at her window every autumn dropping a linen rose into Musset's garden and waiting for a signal that never comes. November sends Musset out through the town to give away the wisdom she has finally acquired at fifty, and nobody will stop to listen. December is her funeral.
