This story contains a good deal of amusing stuff in it, starting with the chapter titles. Many of the puns are pretty lame ("Mount Taine"), but there are some Pythonesque moments and the whole British-lit tone adds to the fun.
My only real objection is the execrable punctuation. "Dance Medusa," one character commands. It seemed as though some comma-eating monster had gone through the text, with only a few commas escaping its ravenous maw. For pity's sake: am I the only one who paid attention in school?
