I have done quite well this month, but I have run into a block with 3 clues:
22A: Mythical Maiden rested, returning her letters? (5). I have ??T?? (I think that if the first letter is replaced by L, this yields another word unrelated to he clue)
23D: Lose it on interrupting court favourite (3,3). I have ??E/?E?
27D: Special police force turned over kind of cell (4). I have ??E?. Again with this one, I think replacing the first letter with S yields another word unrelated to the clue.
