Vanishing Point — Morris West

VANISHING POINT -- THE DANGEROUS EDGE OF THINGS WHERE ALL LIVES AND ALL ROADS CONVERGE

Carl Strassberger may have given up his role in his family's hugely successful financial business to pursue his artistic dreams, but when his brilliant brother-in-law Larry Lucas vanishes after completing the biggest deal of his career, Carl is urgently summoned to find him.

What Carl discovers is that Lucas is not quite the man he seemed. In fact, he suffers from a severe mental disorder that can send his emotions on a roller-coaster ride, between intense depression and manic elation. It is a condition that could have extreme consequences--wild folly on the one hand and suicide on the other. Drawn into the search against his will, Carl must risk everything to track down the sick but cunning man he thought he knew so well, and now suspects he never did.

A story of flight and pursuit, of secrets and lies -- where the normal has no meaning and nothing is as it appears.
