   I’ve tried downloading this puzzle a few times but all I get is an ordinary killer. Love all your overlapping killers and clueless killers and can’t get enough of them!

   Hi Sandra,

   not sure why you are getting an ordinary killer. Look carefully – it’s a 12×12 puzzle, not 9×9.

   4 sub-puzzles overlap heavily so you may not have noticed that it’s a butterfly…

   Thanks. With only half a brain how do I cope? With a large bag of erasers and lots of time!

   Hello, all I can see is a grid without numbers; am I missing something ?

   July 28 is definitely “hard”. After 6 hours of studying, I must not understand the clue on twin nonets, N8
