This is a fine and sympathetic account of Richard's life, and places him more accurately within his times than the many prejudiced accounts that we have become used to.
While clearly sympathetic to Richard, it does not completely acquit him from responsibility for the princes' fate ("The push from the dais was the mortal stroke"), and leaves this as an unsolved mystery, which may, or may not have been to his account (though Kendall seems to lean towards Richard's innocence).
Kendall seeks to fet right inside the mind and heart of his subject, and leaves one feeling real empathy for Richard as a human being. This might not be entirely historical, for how can we know the feelings and thoughts of a person 500 years dead, but it does create understanding.
I was interested to note, primarily, from the Appendices and Notes, that there exist doubts that the skeletons discovered in the Tower are those of the princes. (Actual site of location, age and ages of the bones, unclear references later than 1483, to the Lord Bastard).
