The Castle of Iron — L. Sprague de Camp; Fletcher Pratt

It's like this...

I am a psychologist at a university in Ohio--very solid state, solid job.

What with one thing and another my wife happens to be a fictional character from a poem. This is hard to explain. When she disappears into another world, it is much harder to explain -- particularly to the cops.

When I follow her with a magic carpet, a werewolf, and some spells that don't quite work-- it's impossible to explain.

Unless, of course, you read the book....
