After the revelations in The Rendlesham Incident, Holmes and Skye find they have not one, but two, very serious problems facing them. Not only did their ''UFO victim'' most emphatically NOT die from a close encounter, he was dying twice over – from completely unrelated causes. Holmes must now find the murderers before they find the secret of the McFarlane farm. And to add to their problems, another continuum – containing another Skye and Holmes – has approached Skye for help to stop the collapse of their own spacetime, a collapse that could take Skye with it, should she happen to be in their tesseract core when it occurs. The Case of the Cosmological Killer: Endings and Beginnings is the fourth book in an exciting and popular science fiction and mystery series.
