The Luck of the Bodkins — P.G. Wodehouse

Things on board the R. M. S. Atlantic are terribly, terribly complicated. Monty Bodkin loves Gertrude, who thinks he likes Lotus Blossom, a starlet, who definitely adores Ambrose, who thinks she has a thing for his brother Reggie, who is struck by Mabel Spence, sister-in-law of Ikey Llewellyn, but hasn't the means to marry her. It will, indeed, take the luck of the Bodkins to sort this all out.
