The Daughter of Time by Josephine Tey

This book was recommended by Madeleine L'Engle in her book on writing mentioned below. As with the Robertson Davies books I could not help trying it out and it was very good.

Inspector Alan Grant of Scotland Yard, in a hospital bed recuperating from a broken leg, is getting very bored until one of his friends brings in a collection of portraits for him to look at and "profile." One of the portraits is of Richard III, the king widely thought to have had his young nephews murdered to ensure his succession.
But the detective, who's always thought himself a good judge of faces, sees not villainy, but pain, in the king's face. This triggers a research crusade/"investigation" in which he digs into the historical information, (what there is of it) and tries to find out whether or not there is any proof that Richard did murder the young Princes in the Tower.

The detective's work is aided in this by a young American researcher, who's followed his actress/girlfriend to England under cover of a less exciting research project.

The plot is carried along by the researcher's frequent visits with new developments as he ferrets out facts in this ancient "case."
Madeleine L'Engle said that when this book was written in 1951 it set off several new protests for the innocence and character of Richard III.

The title apparently comes from an proverb on the title page: "Truth is the daughter of time."

This would be an interesting book to read along with watching the movie "Wag the Dog" and/or various articles written about current and past political Adminstrations and ongoing attempts to recolor actual events going on today. This book talks about a lot of the propaganda/misinformation that the Tudors either spread around or else failed to correct during the period after Richard III's death and the beginning of Henry VII's rule.
I'm reading an article in The New Yorker (the large anniversary issue) about the practice of "outsourcing torture" - it lists several examples of US officials sending those suspected of terrorism to 3rd countries (not their own) that widely practice torture during interrogations.
It's interesting that these occurences aren't really widely known by the public either - I wonder whether or not they will be referenced in future school history books?
