But the two succeeding "books" are more tiresome and more unnecessary than the most inferior of the three opening sections -- the first of the two, indeed, is intolerably wearisome, a desolate boulder-strewn gorge after the sweet air and sunlit summits of "Caponsacchi" and "Pompilia". In the next "book" Innocent XII. is revealed. All this section has a lofty serenity, unsurpassed in its kind. It must be read from first to last for its full effect, but I may excerpt one passage, the high-water mark of modern blank-verse: -- "For the main criminal I have no hope Except in such a suddenness of fate. I stood at Naples once, a night so dark I could have scarce conjectured there was earth Anywhere, sky or sea or world at all: But the night's black was burst through by a blaze ---- Thunder struck blow on blow, earth groaned and bore, Through her whole length of mountain visible: There lay the city thick and plain with spires, And, like a ghost disshrouded, white the sea. So may the truth be flashed out by one blow, And Guido see, one instant, and be saved." Finally comes that throbbing, terrible last "book" where the murderer finds himself brought to bay and knows that all is lost. Who can forget its unparalleled close, when the wolf-like Guido suddenly, in his supreme agony, transcends his lost manhood in one despairing cry -- "Abate, -- Cardinal, -- Christ, -- Maria, -- God, . . . Pompilia, will you let them murder me?" Lastly, the Epilogue rounds off the tale. But is this Epilogue necessary? Surely the close should have come with the words just quoted?
