The Ghost Pirates

"The old ship, the Mortzestus, is beset by mysterious phenomena - - shadowy figures emerging from the sea, men hurled from aloft by invisible hands and the vessel itself seemingly trapped in a world of mist. The horrors reach a climax when ghost pirates swarm aboard to sink the ship and only one man survives to tell the story." - - Description by Peter Haining, in "A Century of Ghost Novels 1900 - 2000" (Appendix to his book, The Mammoth Book of Modern Ghost Stories)
