Edna Buchanan's 'Shadows'

Before "CSI: Miami" there was Edna Buchanan. She's worked on more than 3,000 homicide cases, but she's not a Miami police detective.

She's a Pulitzer Prize winning crime reporter who's written 16 books including her latest, "Shadows." Click here to read an excerpt.

Buchanan visits The Early Show to talk about the auction that raised $25,000 for hurricane victims and gave her the name of a pivotal character in this book.

She designs the crimes and then has to solve them herself. Find out what makes a good cold-case detective.

"Shadows" is published by Simon & Schuster, which is owned by Viacom, the same parent company as CBS.
