The White Feather by P. G. Wodehouse

The time of this story is a year and a term later than that of The Gold Bat. The history of Wrykyn in between these two books is dealt with in a number of short stories, some of them brainy in the extreme, which have appeared in various magazines. I wanted Messrs Black to publish these, but they were light on their feet and kept away—a painful exhibition of the White Feather.
