Claudette was a friend of Josephine Baker.
In May of 1927, Lucy Preston, Rufus Carlin, Dave Baumgardner, and Ernest Hemingway go to the Dingo Bar in search of Charles Lindbergh, who is thought to be dead. Hemingway enlists the help of Josephine Baker, who asks around the bar for anyone who might of seen either Garcia Flynn or Emma Whitmore.
Claudette later tells Baker that she's seen Flynn when she was working a corner. Shortly after Baker reveals this information to Rufus and Lucy, Baumgardner spots Emma and Karl at the bar.
