Archie Hunter travels to Cruden Bay, Aberdeenshire, to enjoy a little rest and relaxation in the small seaside village. But his holiday takes an unexpected turn when he begins to see spirits of the dead and an old woman named Gormala tells him he possesses the "Second Sight." According to Gormala, both he and she are Seers, and she proposes an alliance to solve the centuries-old "Mystery of the Sea."

But the sea holds more mysteries than one. Archie discovers a chest full of old documents he believes contain a coded message revealing the location of a lost treasure of the Spanish Armada. And then there is Marjory, the beautiful American girl Archie saves from drowning. Who is she, and why is she being pursued by a vicious gang of criminals and the American Secret Service?

This edition, the first published in the United States in more than a century, features the unabridged text of the first edition as well as an introduction and notes by Carol A. Senf, one of the world's foremost Stoker scholars.
