Dialogues of the dead or paronomania!

In the Beginning was the Word...And the Word was Murder.
A motorist dies after plunging off a bridge...A motorcyclist is found dead after a fatal encounter with a tree. Two apparently innocuous tragedies...until two Dialogues are submitted to a local literary competition, claiming responsibility for the deaths. But has anybody heard the Word? When a beautiful, unscrupulous journalist meets her Maker in fact, and then in fiction, as victim of The Third Dialogue, Dalziel and Pascoe take note and find themselves involved in a deadly duel of wits against an opponent known only as the Wordman: a brilliant sociopath who leaves literary clues in his wake...and who hides in plain sight. Contestants, are you ready?
