You already know the story of what happened to the Titanic. But what about another famed ocean liner, the Lusitania?

Erik Larson, author of The Devil in the White City and In the Garden of Beasts, turns his pen now to how, in the midst of World War One, this luxurious ship got caught in a web of wartime intrigue and ultimately met a grisly end. He joined Boston Public Radio to discuss his new book, Dead Wake: The Last Crossing of the Lusitania.

"What everybody knows about the Lusitania is actually not much," Larson said. "The common wisdom is World War ship, hit by torpedo, sinks, America enters the war. That's not the way it happened," he said.

"The story is essentially about the voyage and the experience people had aboard the ship. That's why I kind of wanted to go into it," Larson continued. "It was a pretty horrendous experience."
