William Tell Told Again-P. G. Wodehouse

Eric, artist for the king, has created a marvelous painting of a royal wedding. It is finished except for the face of the queen, which appeared to him in a dream. When he awoke, he had forgotten the form of the features. Obsessed with recapturing this vision, he goes on a quest to find the woman because he cannot paint another stroke until he sees those eyes again. During his journey, he discovers much more, perhaps even the true meaning of his dream and of his life. - Summary by Amy Gramour
