Factor30-I think we would all agree that the compiler may have erred and that the wordplay suggests that the answer was intended to be W RY NESS
(ie Wife+railway+head), were it not for the fact that the clue only allows 6 characters, not 7. However, the only possible legitimate word that will fit and bear some relation to the clue, is WRYEST (WryISH does not seem to appear in any dictionaries that I have looked at).
