Wodehouse was criticised for repetition very early on.
In the introduction to "Summer Lightning" he wrote...
"A CERTAIN CRITIC – for such men, I regret to say, do exist – made the nasty
remark about my last novel that it contained ‘all the old Wodehouse
characters under different names’. He has probably by now been eaten by
bears, like the children who made mock of the prophet Elisha: but if he
still survives he will not be able to make a similar charge against Summer
Lightning. With my superior intelligence, I have outgeneralled the man this
time by putting in all the old Wodehouse characters under the same
names. Pretty silly it will make him feel, I rather fancy."
