In ,is
speaking with Myrtle's sister, . Nick reveals that he has recently been a guest at one of 's
parties, and it is Catherine who then says, about Gatsby, "they say he's a nephew or a
cousin of Kaiser Wilhelm's. That's where all his money comes from." Kaiser Wilhelm was the
German Emperor from 1888 until his abdication in 1918.

In the same
conversation with Nick, Catherine also says that she is "scared" of Gatsby, and that

are most strongly suggested by Gatsby's relationship with .

There are, in the
early chapters of the book, lots of curious rumors about Gatsby besides Catherine's suggestion
that he is a relation of Kaiser Wilhelm. In , for example, at one of Gatsby's parties, one of
the guests suggests that he "killed a man once," and another proposes that "he
was a German spy during the war."
