A delusional ghost, a mischievous book, and the hapless Olivier keep things humming in this second entry in the Cat's Eye Corner series. The story begins with our hero, Olivier, examining his discovery from his last adventure (as related in Cat's Eye Corner): a most unusual book called Enquire Within Upon Everything. Not only is this book an encyclopedia of arcane and fascinating information, but strange things begin to emerge from its pages: a wisp of puckish smoke from the eruption of Mt. Vesuvius that causes no end of trouble in the house at Cat's Eye Corner; a ghost named Peely Wally who refuses to believe that he is a ghost; and a tiny Chinese "ink" monkey who snatches up Olivier's pen friend, Murray Schaefer, and disappears with him through one of Cat's Eye Corner's mysterious doors. Olivier pursues the ink monkey and a new adventure begins, involving, among others, a suave and chatty moose-man called the Schmooze and a nasty entrepreneur and child-thief, The Emperor of Ice Cream. This second book in the trilogy is full of clever wordplay, fascinating characters, and a nail-biting life-and-death quest that reinforces the values of loyalty and friendship.
