There's another series of book that may not be familiar to U.S.
readers. They're the Bartholomew Bandy books, written by Donald Jack,
and are aimed at adults. An absolute hoot! The real-life Billy Bishop,
Canadian WWI ace, seems to be the inspiration for the character, but
unlike Bishop he is a klutz for whom everything turns out to his
credit. Similar to the luck of Inspector Clouseau of the Pink Panther
movies. The first four or five Bandy books are especially funny.
Used-book stores usually have a few around. Might find them on the
'net, too. Don't read them if you have a weak bladder...
