Hmm, this is rather puzzling.
I've completed the grid, got the 8 'unfortunate victims', the song and both the name of the performers and the 'perpetrator'.
But here's my problem, the preamble says to use the initial letters of the unfortunate victims and colour the cells appropriately, so for the one beginning K, for example, how does that equate to a colour, or the 2 initials of the lady who says "good gracious"?
I've tried looking at the individual letters in Chambers and also grouping them together to see if they are an anagam of a colour, but with no luck. I also tried adding the initial letters to the rest of their answers, but again, nothing.
Usually when I'm stuck it's because, although I know what I'm supposed to do, I'm just not sdmart enough to work it out. But, in this instance, I truly have absolutely no idea how single or paired letters lead to a colour?
