I not only went through 1/2 a dozen of my books books, but also tried to find what you were talking about on line and found nothing. I thought that I had somehow missed something and was going to ask you, today, to tell me where you had found out about this info. LOL...it was driving me a bit crazy! :-)
I too was somehwhat "off" about the timeline of the finding of the two small skeletons; off by centuries, for the first findings, sadly. I got my dates jumbled. The first "find" was centuries earlier, but the bones have been moved, reburied, found again when work was being done and yet one more time after that. YIKES...and still nobody knows what really happened to the "little Princes"! I love a good mystery, but wish that there were more facts/an ending to this one.
I also remember a scene from Rosencrantz and Guildenstern Are Dead - as told from the other side of Hamlet that took in a scene from the Tower.
