Well you cound read these, and become unconvinced:
The Princes in the Tower by Alison Weir. The author argues convincingly that Richard III did indeed arrange the murder of his young nephews, King Edward V and Prince Richard, so he could seize the throne.
The Princes in the Tower by Elizabeth Jenkins. Did Richard III have his nephews killed? The author of this book says yes.
Or read this, and become re-concinced:
The Mystery of the Princes by Audrey Williamson. The author believes the princes were not murdered. This book won the 1978 Crime Writers' Association Gold Dagger Award for Nonfiction.
