Even with 'Three Days of the Condor,' I wanted to do a thriller. But I was still concentrating on the Faye Dunaway-Robert Redford relationship in that film.

One often hears of writers that rise and swell with their subject, though it may seem but an ordinary one. How, then, with me, writing of this Leviathan? Unconsciously my chirography expands into placard capitals. Give me a condor's quill! Give me Vesuvius' crater for an inkstand! Friends, hold my arms! For in the mere act of penning my thoughts of this Leviathan, they weary me, and make me faint with their out-reaching comprehensiveness of sweep, as if to include the whole circle of the sciences, and all the generations of whales, and men, and mastodons, past, present, and to come, with all the revolving panoramas of empire on earth, and throughout the whole universe, not excluding its suburbs. Such, and so magnifying, is the virtue of a large and liberal theme! We expand to its bulk. To produce a mighty book, you must choose a mighty theme. No great and enduring volume can ever be written on the flea, though many there be who have tried it.

Over the souls of men spread the condor wings of colossal monsters and all manner of evil things prey upon the heart and soul and body of Man. Yet it may be in some far day the shadows shall fade and the Prince of Darkness be chained forever in his hell. And till then mankind can but stand up stoutly to the monsters in his own heart and without, and with the aid of God he may yet triumph.
