This is the sixth and last of Dunnett’s Lymond Chronicles, following on from The Ringed Castle. Each chapter is preceded by an epigraph in French and there are copious quotations/song lyrics in French throughout.
Among other incidental historical goings-on such as the French capture of Calais from the English, the French war against the Spanish (in both of which Lymond has a guiding role,) and the wedding of Mary Queen of Scots to the Dauphin, the main plot concerns the unravelling of Lymond’s seemingly uncertain parentage, an unravelling performed in the main by Philippa Somerville, whom Lymond married in The Ringed Castle to protect her honour, a union which remains unconsummated and from which Lymond is desirous of an annulment (as, to be fair, is Philippa.) The reasons for this desire are complicated and not entirely voluntary and obstacles continue to put in its way but both contract promises to future marriage, in Lymond’s case to Catherine d’Albon, daughter of the Maréchale de St André, in Philippa’s to Austin Grey.
Lymond is neither ashamed nor guarded about his past amours – he has a son, Kuzum, by the deceased Oonagh O’Dwyer; a former lover, Guzel, left behind in Russia, and in this book he beds the Maréchale (or, rather, she beds him) before the proposal to her daughter. When Catherine asks if she’s agreed to marry a libertine she gets the reply, “‘Everyone marries libertines,’ Lymond said. ‘But not everyone knows it beforehand.’”
A minor sub-episode reveals the young Scottish Queen, under the influence of her de Guise uncles and prospective father-in-law, King Henri II, secretly agreeing that if she died childless the throne of Scotland should pass to France. This does not go down well with delegation of Scottish nobles sent to witness Mary’s wedding, who are obliged to keep their knowledge of the pact secret but Lymond goes so far as to warn Mary that such an outcome would meet with all but universal opposition back home.
Also contributing to the proceedings, helpful in relieving Lymond of a burden of sickness as well as in the resolution of the parenting issue, is one Nostradamus.
While the level of research and historical detail are impressive and incident is never far away once again Dunnett’s writing and dialogue lacks clarity.
Pedant’s corner:- hiccoughing/hiccough (it’s not a cough; hiccuping/hiccup,) “Daedalus’ honeycomb” (Daedalus’s,) palinquin (palanquin.) “After Russia, campaigning in France, would be like” (that second comma is needless,) “the aesthetic figure one would have thought from his reputation” (‘ascetic’ makes more sense in context,) Luxembourg (sometimes here spelled Luxemburg, which may have been a rendering of the usage of the viewpoint character of the moment,) “the Vidame de Chartres’ voice” (the final ‘s’ in Chartres is not voiced so its possessive is certainly Chartres’s,) “like Crassus’ lamprey” (Crassus’s,) “staunch the bleeding” (stanch,) alambic (usually spelled ‘alembic’,) “his language than had not been moderate” (his language then had not,) a missing comma before a piece of direct speech, “there had been nothing demanded of Philippa which needed intrude on this relationship” (which need intrude; or, which needed to intrude.) “The pavilion of the Duke de Guise and that of his brother d’Aumale were empty” (The pavilions,) “was tinging the cloth” (tingeing; tinging is something bells do.) “One of the Count of Egmont’s foraging parties had acquired half a dozen wagons of grain and were occupying the village” (One … was occupying,) “tell the prayers” (they were musicians, not supplicants: ‘tell the players’,) “a Brazilian dancer” (I wondered if Brazil was known as such in 1558 but the term is apparently from around 1506,) a missing full stop.
