I am glad this was not as difficult as it first looked.
I have solved it except for 19D, which is unclued.
The treatment given to 29D and 31A should apply to 19D also.
But I cannot find a word other than one that applies to the type that
all 3 (includes 2D) are. (At least the last 4 letters)
Hankir, 19D is not just of the same type as 31A and 2D, but comes from the same studio. Apparently, he is a sleazy, obnoxious member of the species, who openly abuses 2D.
Yes, pretty easy this week, but still good fun. Could we though now Summer is definitely over request a break (sorry !) from 'on vacation' in clues ? It's becoming as hackneyed a device as 'sandwiches', and similarly stands out a mile.
