The Black Wheel

On an innocent Caribbean cruise, a clipper ship is struck by a hurricane. After three days of drifting with a dead radio transmitter, the survivors spot an island and anchor in a lush lagoon. They soon discover a pirate ship half-buried in the sand -- and begin an ill-advised attempt to unlock its secrets. That's when the nightmare begins. The first seven chapters were penned by Merritt, the most popular genre writer of his era, and the remaining twenty chapters completed by Bok following Merritt's death.
