Hi cassie, muckle41, topsy47
Heres my suggestions
3d frantic. 14d repulsive. 1d colonizes. 8a erstwhile. 7a hours. 13d roman blind. 10d tie up in knots. 15a red tape. 23a round trip. 18a. long drawn out.
But I'm not sure about 16a clue dammed ?t?m?e? - I think it must be stymied or stumped (as in "i'm dammed if I know the answer = I could be
stymied or stumped). What do you think?
