P advertises in a daily newspaper that he will give a prize of 10,000 to the first person to swim the English Channel and back during the month of August. F, who has read the advertisement, sets off on August 1st and reaches the coast of France on 2nd August. On that day, a further advertisement appears in the same newspaper stating that the offer of the prize has been withdrawn. On 3rd August F completes the return swim to England. Can he recover the prize money?
