Welcome to Greeve. A sun-drenched backwater world, where people earn their keep from the sea. It's nowhere important, far from any of Mankind's petty politics and intrigues. Few of its residents are more familiar than old John, who's been fishing its waters for decades. He keeps to himself, mostly. Nobody really knows him. No one knows where he came from. But how dangerous can he be? Then another off-worlder settles in, with no apparent goal other than devoting the rest of his days to local drugs and local women. Old John is horrified to recognize him at once. How dangerous can Old John be? As dangerous as any man alive...
