I thought I'd reread the House Of Noccolo series several times, and I have - but only as far as To Lie With Lions. The last two books I've only read the once, which I find at once slightly shameful, but also delightful since there was so much I'd forgotten that it was almost, if not quite. like reading it for the first time. 

Nicholas has gone to Poland, outcast and rejected by family and friends and associates for what he did in Scotland, relentlessly punishing himself by cutting himself off from everything he loves, hanging out with the pirate Benecke, who is determined to make him into a version of himself, for a winter of rough and bloody sport, though not without an ulterior motive. The impending piratical life is interrupted, however, by the arrival of familiar faces, including those of Julius and his new wife, and soon Nicholas is prodded and persuaded and bribed and cajoled to journey to the Turk-threatened Crimea, while at home, his family and friends are drawn into the ineptly-prosecuted war of the Duke of Burgundy and look deeper into Nicholas's past which slowly reveals a real current threat to them all. 

Vivid and richly detailed as always, the journey of Nicholas, who had given up on himself and everything, but is roused to act to protect the people he loves and possibly climb back to find some sort of redemption, is epic and steeped in mysteries and secrets and terrible revelations, culminating in a dreadful, disastrous snowbound battle that turns into a continent-shaking rout. Dunnett at the full height of her powers, the energy and the skill and the dexterity of her plotting absolutely unflagging.
