I read The Prince of Rags and Pathes a few months ago, and I enjoyed it. However, since then i have found out the truth about Richard III: he did not order Sir James Tyrell to murder his nephews, as this book suggests. I would not recommend anyone read this book, unless they want to be introduced to the widely believed but totally incorrect story. I would instead recommend "The Daughter of Time by Josephine Tey, which answers this "riddle" of the Princes in the Tower. Apart from this one book, the rest of Terry Deary's books, especially his "Horrible Histories" series, are an entertaining and informing look at historical events. But please, do not believe this one book: while the Marsdens are fictional, so too is the plotting, murdering Richard III portrayed in it.
