Underwater explorer Richie Kohler (of “Shadow Divers” and “Deep Sea Detectives”) has released a new book, “Mystery of the Last Olympian: Titanic’s Tragic Sister Britannic.” It narrates the rise of this class of luxury ocean liners to the fateful day in 1916 to the expeditions to find the wreck, beginning with Jacques Cousteau, who located it in 1975.

Finally, in July 2015, Kohler and a small team were able to document their findings to answer why all the engineering solutions built into the mighty Britannic could not save it from sharing the same fate as Titanic.
