Thomas Pynchon said this quote

“ It appears that some part of Slothrop ran into the AWOL Džabajev one night in the heart of downtown Niederschaumdorf. (Some believe that fragments of Slothrop have grown into consistent personae of their own. If so, there's no telling which of the Zone's present-day population are offshoots of his original scattering. There's supposed to be a last photograph of him on the only record album ever put out by The Fool, an English rock group—seven musicians posed, in the arrogant style of the early Stones, near an old rocket-bomb site, out in the East End, or South of the River. It is spring, and French thyme blossoms in amazing white lacework across the cape of green that now hides and softens the true shape of the old rubble. There is no way to tell which of the faces is Slothrop's: the only printed credit that might apply to him is Harmonica, kazoo—a friend. But knowing his Tarot, we would expect to look among the Humility, among the gray and preterite souls, to look for him adrift in the hostile light of the sky, the darkness of the sea. . . .) ”
