I read a book today. The first puzzle is about the invitation letter. There is no signature on the invitation, only some fruit stickers. Why did Charlie say he gave advance notice?
Apple, apple, nectarine, kiwi fruit, bayberry and bayberry, the initial letter A N K W, where A N may represent time or date 0 1. 14 KW may be the abbreviation of a place, and the color can also be used as a reference. Charlie said that it was possible that he had been told the time and place before receiving the invitation.
