What gossip about Gatsby does Nick lesrn at the party?

Catherine claims that Gatsby is somehow related to Kaiser Wilhelm, the much-despised ruler of Germany during World War I.

“Really? I was down there at a party about a month ago. At a man named Gatsby’s. Do you know him?”

“I live next door to him.”

“Well, they say he’s a nephew or a cousin of Kaiser Wilhelm’s. That’s where all his money comes from.”

“Really?”

She nodded. “I’m scared of him. I’d hate to have him get anything on me.”
