This book, as well as Enid Blyton's other "_____ of Adventure" books (Ship, River, Sea, Island, Castle, Circus, etc) were all books that I must have read at least a thousand times each when I was a child. The daunting implausability of the escapades of the four adventurers from boarding school with their unpredictable, train-whistling parrot Kiki never failed to pique my imagination, no matter how many times I read them.
The battered copies of these books that survived my childhood I now encourage my own children to read, which they devour with the same relish that I did. These books are treasures, and I wish that there could be multitudes of them.
