Bell, Book and Candle
Sidney Redlitch, the author of a best-selling book Magic in Mexico, suddenly appears in Shep's office (thanks to a little magic trick that just takes him there). Gilliam and Pyewacket have him arrive when she finds out Shep wants to meet with him about writing a book together. Redlitch is befuddled and confused but soon catches on.  Redlitch is doing research for a book on witches in New York. He gats an "inside" helper when Gillian's warlock brother Nicky offers to help in exchange for a share of the profits.
