Lig Lury Jr is the fourth editor of The Hitchhiker's Guide to the Galaxy. When that book acquired by Megadodo Publications and put on a sound financial footing, it allowed him to embark on lunch breaks of such breathtaking scope that even the efforts of recent editors, who have started undertaking sponsored lunch-breaks for charity, seem like mere sandwiches in comparison.
In fact, Lig never formally resigned his editorship - he merely left his office late one morning and has never since returned. Though well over a century has now passed, many members of the guide staff still retain the romantic notion that he has simply popped out for a ham croissant, and will yet return to put in a solid afternoon's work. Strictly speaking, all editors since Lig Lury Jr have therefore been designated Acting Editors, and Lig's desk is still preserved the way he left it, with the addition of a small sign which says "Lig Lury Jr, Editor, Missing, presumed Fed".
Some very scurrilous and subversive sources hint at the idea that Lig actually perished in the Guide's first extraordinary experiments in alternative bookkeeping. Very little is known of this, and less still said, probably because no one wants to be sued to smithereens.
