Well stone me...I never knew that about Rebus. I only know the Detective which was clearly part of your cunning plan...and by Jingo it worked!!....and spookily I am currently in the middle of reading a (yet another!) Rebus book

To be honest neither did I- I looked it up for the purposes- funnily enough the det. idea came after. Lovely that you and I seemed to continue a running theme! BTW really wanted to include last jedi in the ade group as it surprised me! but not enough crossovers :(
Nice couple of grids for the detectives out there!

Oddly enough, I knew about rebus, but left out instruction manual, because that does not have to have pictures, so the red herrings got me, especially as I assumed Bottom would be in the Shakespeare group.

I think that's the most crossovers/ red herrings I've ever used, if you include the false group, so easy to get snagged!

Yep, tricky indeed. Top marks.
