At moderator's request, I've been asked to limit the number of batched clues to a maximum of four. Cheers & here are the clues:
15a. Woman's name mentioned by prince
FRAILTY
21a. Obliging, unlike the king's head
EASY
25a. Create a lot of interest in the plot
INTRIGUE
29a. Basic senseless deception
UNDERLYING
Parses for the above please.
