My father was reading these paperbacks at home, a 23-volume set of the Vatican Miracle Examiner series. ◆ The Black Academy ◆ Satan's Judgment ◆ The Golden Darkness ◆ The Melody of the Millennium Kingdom ◆ Blood, Roses, and the Cross ◆ Laplace's Demon ◆ The Game of Angels and Demons ◆ The Apocalypse Madonna ◆ The Ice Wolf that Swallows the Moon ◆ The Sinless Apostles ◆ The Detective in the Solitary Confinement ◆ The Banquet of Demons ◆ The Descendants of Solomon ◆ The Paradise Cross ◆ Zombie Murder Case ◆ Twenty-Seven Elephants ◆ The Bells of Gévaudan ◆ The Crossroads of Angels and Fallen Angels ◆ Adam's Temptation ◆ The King of Kings ◆ The Three Mysterious Fugues ◆ Where the Angelic Host Leads ◆ The Secret Garden I don't think there are any unreadable stains or damage, but I haven't checked every page. I would appreciate it if you could assume there might be small scratches, stains, creases, and folds. The spines and covers don't seem to be yellowed, but there might be some on the page edges, so please consider them as used books. Please be aware of this if you are at all concerned. It seems to be a series that has also been made into an anime, so I hope those who want to read it as the original work will enjoy it.
