Many are familiar with Douglas Adams's classic Hitchhiker's Guide to the Galaxy series, but few know that these books started out as a multi-part series performed on BBC radio. This installment, part four, is a robust radio dramatization of So Long and Thanks for All the Fish. The Earth has miraculously reappeared and Arthur Dent is in love with the otherworldly Fenchurch, but Ford Prefect has an idea that might burst Arthur's happy little bubble. What is really going on with Arthur's dream girl, where have all the dolphins gone, and what was their departing message to mankind?
