There is not much truth to be found online to defend Torquemada but the book below gives us the truth about him and this book is available from Tan Books here.
"Refutes the many lies about the Inquisition raised by the enemies of the Church. Shows why it was instituted, the purpose it served, its long-term effects, and why it preserved Catholic countries from the infamous witch-hunts besmirching Protestant history. All this is achieved by narrating the stories of six Grand Inquisitors. Exonerates the Church of all wrong-doing. Really dispels the lies about this institution."
