Walking a Thin Line

Three years pass, and the police are still unable to find the ''Extract Killer,'' whose murder spree now covers four states.  His modus operandi is always the same:  an injection, into the heart, of an extract of Nerium oleander.  And each of his victims has been found guilty of killing or maiming while driving drunk.

Only one detective is on the right track.  Hugh Miller is convinced that Loring is his man, but he can''t find any concrete evidence.  How many more murders will Loring commit before Miller is able to stop him?

I. S. Grant''s Walking a Thin Line is a taut, gripping detective story.  It is also a fascinating and frightening look into a killer''s mind.
