Join Kathleen Martinez, criminal lawyer turned maverick archaeologist, as she searches for Cleopatra's lost tomb. Very little evidence remains of Egypt's last queen, but a radical new theory has led Kathleen to look where no one else has dared -- and her hunch is paying off as she stuns the archaeological establishment with her discoveries of incredible artifacts, a network of mysterious tunnels, and even a vast city of the dead dated to the time of the Queen and her Ptolemaic dynasty. Now Kathleen has made her biggest breakthrough so far: a 35-meter deep underground shaft that, according to the experts, has all the hallmarks of a royal burial shaft. Could Kathleen be closing in on Cleopatra's final resting place?

On June 11, 1962, bank robbers Frank Morris and Clarence & John Anglin launched a patchwork, raincoat raft into the frigid waters of San Francisco Bay surrounding Alcatraz Prison.

Putting their theory to the test, the Dutchmen are recreating the daring escape as closely to the original as possible, right down to launching their own raincoat raft into the bay. Will they make it through the treacherous waters to safety or be swept out to sea? And can they prove once and for all what happened to the escapees?
