Sherlock and Sci-Fi Christmas

This week, we'll follow the clues to decipher how Sherlock Holmes has stayed fresh for more than a century. We'll meet "Sherlock Holmes in sneakers" — 5^th grade detective "Encyclopedia Brown" — and also the creator of hit TV show House, whose powers (and weaknesses) are modeled on Holmes'. Plus, we'll hear a sci-fi tale with a holiday twist written by Kurt Andersen.
