C4 Hints: You could justifiably call this clue either a charade or a ddef - I've seen both before for the used clue mechanism. One word in the clue refers to a two-word phrase.
none of the dictionaries i can find actually list 'lady-killer' as a lady who kills / person who kills ladies which feels like a fairly obvious definition, so it's possible that that's what's meant by the hint
@GentlePurpleRain I think this is TIME IMMEMORIAL with the enumeration being slightly wrong (should be 4, 10) which is *THEYEARMMMMLIIITO lacking HTY (regular HisTorY)
