Hi lady bee and kace - I can not see my way with the clue for 48 either, or for that matter, the clue given on the other thread for 27. Thanks for extra clue for 99 by the way - great - still had to work at it but got there.
winnie - loose suggests anagram of 'let' and it's inside a word for plenty. Answer is unusual word for something that doesn't get drunk e.g. dregs or sediment.
