  Had to cheat ... Oh, Kay, Karen -- durr, I thought that was wrong for some reason.
  While cheating, I found this tidbit:
   Robert Heinlein reported that Doc had planned a seventh Lensman novel, set after the events described in Children of the Lens,  which was unpublishable at that time (the early 1960s).  Careful searches by people who knew Doc well (including Fred Pohl, Doc's  editor, and Verna Trestrail, Doc's daughter) have failed to locate any material related to such a story; Doc apparently never wrote  any of it down.  Doc told Heinlein that the new novel proceeded inexorably from unresolved matters in Children, a statement easily  supported by a careful reading of Children. |
