is at work behind the scenes at an ancient English university in our familiar reality, subtly corrupting the faculty by mundane means - manipulation of academic politics, offers of tempting career advances and of lucrative real estate deals. The terrifying deviltry behind it becomes only gradually visible to the reader. At least to this reviewer, it seems entirely plausible to consider the one as an early draft of the other". Alastair Fowler, Regius Professor Emeritus of Rhetoric and English Literature at the University of Edinburgh, to whom Lewis served as a doctoral supervisor, wrote in 2003 that he saw portions of The Dark Tower including the Stinging Man and discussed them with Lewis in 1952. Two quantitative stylometric analyses have compared The Dark Tower to other books in the Lewis space trilogy. Both analyses have supported the perception that, for whatever reason, the style of The Dark Tower is atypical of that employed by Lewis in the trilogy. The first concluded from examination of a portion of The Dark Towers text that "with respect to the frequency of single letters and particularly letter pairs, The Dark Tower fragment represents a different style than the books comprising Lewis's deep space trilogy." The second concluded that "vocabulary usage in The Dark Tower differs from that predicted by Out of the Silent Planet and Perelandra." Suggested developments Walter Hooper noted, in his afterword, that Scudamour's fiancee is once given the surname Ammeret, and suggests a basis in the characters Sir Scudamour and Amoret in The Faerie Queene Book III. Amoret was carried off by an enchanter and had to be rescued. Another allusion to note is the probable reference of Orfieu to Sir Orfeo, a medieval narrative poem merging the Orpheus myth with the trip to fairyland. The construction of the tower is clearly important. Lewis's time-lines are quite coherent in terms of the science fiction of his generation; it is often forgotten by readers that he was seriously interested in science fiction long before it was fashionable. In terms of the law that "Any two time-lines approximate to the exact degree to which their material contents are alike" the tower is obviously a repeat, on a grand scale, of the Othertimers' successful but small experiment with a railway shed constructed in the same space as ours. However, although Lewis was a reader of all sorts of science fiction, he himself was not
