Rachel Lance will speak about her successful detective work uncovering the story behind the sinking of the Confederate submarine the HL Hunley.  Deployed in the 1864 battle of Charleston harbor, the HL Hunley sank the USS Housatonic before it disappeared as well, killing its crew and leaving no visible wreckage.
