FROM THE EDITOR

istorians come to their subjects in different ways. Author Erik A. Petkovic Sr. has long been a popular dive site. But Petkovic, an avid diver, felt compelled to look deeper, and found a human story of determination and loss. Petkovic credits the job he had at the time, as a special agent with the U.S. Secret Service—someone charged with protecting his country’s leaders—for fueling his sense of curiosity and history. “It is difficult to work at the White House and not be affected by it,” he says. You’ll find the remarkable sum of those parts on page 30, in his story “Death of a U-boat.” Enjoy.
