'Murder Room' Sheds Light On Cold Cases

PHILADELPHIA - The popular TV show "Cold Case" is about a Philadelphia Police Department unit that tries to solve old cases that were never resolved.

But where do cold case units turn when they can't find answers?

It's an even more elite unit of retired detectives based here in Philly called Vidocq – an international society of forensic experts who consult, free of charge, on baffling murders.

Now, their secrets are revealed in "The Murder Room: The Heirs of Sherlock Holmes Gather to Solve the World's Most Perplexing Cold Cases," written by former Inquirer staffer Mike Capuzzo, with the help former FBI Special Agent William L. Fleisher.

The book is at once terrifying and satisfying, revealing gruesome details of cases. Some will be familiar.

Capuzzo and Fleisher joined "Good Day" on Wednesday morning to discuss the book and some of those cases.
