Several extremely rich men have died under suspicious
circumstances, and Karl Zweig, a professor of philosophy, has reason to
suspect they were murdered by his former student, Gustav Neumann, a
brilliant young man who had once espoused the desire to become a master
criminal. When he observes Neumann in the company of Sir Timothy
Ferguson, a wealthy and sick old baronet, Zweig believes he may soon be
Neumann's next victim. But as Zweig races to gather evidence against his
old friend, he begins to be unsure whether any murders have been
committed at all. Instead, Neumann may be involved in something even
more disturbing and bizarre than anyone could ever imagine . . .
