As Road Rage begins, Chief Inspector Wexford is walking through Framhurst Great Wood, just outside his beloved town of Kingsmarkham, for what he tells himself will be the last time. He can no longer bear to look at the natural beauty that will soon be despoiled by the construction of a new highway. Wexford rather despairs of the project; his more sanguine wife, Dora, is active on a committee to save the threatened land.

Others are more desperate to achieve their end, and their means include the taking of hostages, including Dora, and the threat to begin murdering them.

How Wexford and his dedicated team of police officers race against time to learn the identity of the kidnappers and discover the whereabouts of the hostages will rivet readers who delight in following the intricate details of an intensive police investigation. But, as in every Ruth Rendell novel, the mortal drama raises political and moral questions that are not resolved with the closing of the case, and that apply far beyond the limits of Kingsmarkham.
