I haven't tried that, Brendan. I read a biography of Thomas Cromwell, and it so differed from the person depicted in "Wolf Hall" that I haven't been moved to follow it up.
The C J Sansom "Matthew Shardlake" novels are fascinating, though. The one set in York is very much based on Henry VIII trying to suppress rumours that Edward IV was illegitimate, so the marriage of Henry's father to Elizabeth of York did nothing to legitimise his very dubious claim to the throne.
