9a Caught, having left company, making illegal copy (5) - CLONE
I read this as C(aught) + L(eft),with the remaining 'ONE' coming from 'Company' - but I can't think of an example where they might be synonyms. Would appreciate help with this.
My mistake was getting fixated on 'Left' being L (a deliberate trap, I think, by the setter that I walked straight in to). Thanks again Rusty, thanks Mamya.
