I am reading a book about Catherine of Aragon, first wife of Henry VIII. It does tell about the death of Warwick so that her father Ferdinand (and Isabella), would consent to the marriage since the inheritance would not be contested. Catherine found out that her marriage was started with a murder and years later bestowed kindnesses on that family in recompense. In the Ferdinand and Isabella marriage, she was actually the stronger and smarter ruler, even leading troups into battle against the Moores.
In a separate line, the book also described riots in London because foreigners with skills had successful businesses and were putting native English out of work. Riots occurred and people were executed. A little like the Brexit fuss, where one of the issues is Polish plumbers coming to England and doing better work than the native English.
I like Alison Weir and David Starkey as writers.
