In the excerpt from P.G. Wodehouse's "Carry on, Jeeves," a character is expressing urgency and a bit of impatience regarding a visitor. He instructs Jeeves, his valet, to inform the visitor to hold on if he arrives while the character is not present. This reflects the character's somewhat hasty temperament and perhaps a sense of importance regarding their schedule.

The phrase also showcases Wodehouse's signature humor and the lighthearted banter between characters. The mention of getting ready, with descriptions like "mes gants" and "mon chapeau," illustrates the character’s whimsical personality and the playful nature of the narrative, highlighting the charm and wit found throughout the book.
