Following Slaney's theory of an anagram within the clue with a letter missing - I am not sure if the answer in Dreamt or dreamo? .... 20d. 6 letters. D - E - M - Detected aroma about attractive person. Anyone got an answer?
Given the circumstances I would go for Dreamo as that could be a noun as the clue requires it to be. Dreamt is the past participle of the verb. Not happy with it though.
