I love history's mysteries. I am always intrigued when historical myths are debunked. This prompted me to watch "The Princes in the Tower" episode of Secrets of the Dead." Phillippa Langley was the force that successfully found Richard III in that parking lot, her journey and hypotheses verified by DNA testing. So, I followed her in the quest toward learning the fate of Richard's two nephews, that would upend the story we all learned about their incarceration in the Tower of London. The episode presented several documents around Europe, telling a couple of tales about each of the two princes. There was a middle Dutch translation of first person account (presumed to be originally in French, although this was not available for this documentary) asserted to be written by the younger nephew, Richard, himself. Another storyline followed the elder prince's travels to Ireland. The stories were interesting. And anecdotally, several experts (i.e., secondary sources) the documentary reported, believed all presented evidence to be authentic.
However...
There was no mention of testing these documents for authenticity, not the paper or ink, nor were they reviewed for any linguistic confirmation / support of their veracity. Perhaps the most obvious omission was the lack of DNA testing of the remains of the two bodies, currently interred in Westminster Abbey, presumed to be the two boys. If this was a matter of denied permission on the part of English authorities, this was not mentioned. Additionally, Ms. Langley's clear investment in proving her presumptive assertions, was ripe for skewing the outcome turning her supposition into a self fulfilling prophecy. The doc's summary, presented as a confirmation by the lawyer whose skepticism was meant to be the counterweight to her bias, was instead written in conditional verb constructs, including phrases such as "may ... possibly be ... could have been ...," but void of factual verification.
If you're looking for a good yarn, enjoy the ride. If you're interested in factually supported reporting, take a pass.
