My wife says I am "obsessed" with crosswords I counter by saying that it is far better than drinking,gambling etc and extremely cheap(bar the cost of stamps)I also put her name as well as my own when entering to placate her-she also has an annoying habit at getting ones I am stuck on to finish them even though she has no interest in the word play etc. Well done on the Spectator -if you go to the link I gave before you can get one every Thursday The "themes" have ranged from airlines to Thomas the Tank Engine with Spielberg films as well -the title hints at the theme and quite often you have to highlight different parts of the crossword including once the actual crossword number -that is part of the fun.
Regards happy crosswording!
