A brilliant sci-fi novel from one of the last century's most influential pop cul
ture figures Substance D - otherwise known as Death - is the most dangerous drug
ever to find its way on to the black market. It destroys the links between the
brain's two hemispheres, leading first to disorentation and then to complete and
irreversible brain damage. Bob Arctor, undercover narcotics agent, is trying to
find a lead to the source of supply, but to pass as an addict he must become a
user, and soon, without knowing what is happening to him, he is as dependent as
any of the addicts he is monitoring.
