The House of Niccolo 05 - The Unicorn Hunt

Last encountered in Scales of Gold , ruthlessly determined Flemish banker/knight Nicholas vander Poele, protagonist of Dunnett's House of Niccolo series, embarks on a new set of adventures that take him across late-15th century Europe from Flanders to Egypt. After a useful recap of the saga's previous four volumes, Nicholas sails to Scotland, where he confronts his archenemy, Simon de St. Pol, who may be the father of the child whom Nicholas's wife, Gelis van Borselen, is carrying. Months later, back in Flanders, vengeful Gelis, in order to punish Nicholas for fathering an illegitimate child by her sister, hides her newborn boy.
