James Patterson & Mike Lupica: Traveler (USA 2027)

From the Publisher:
An investigative journalist goes searching for her next blockbuster case -- then wishes she hadn't found... The Traveler.
Gracie Bronte is a prize-winning true-crime writer. Christian Walshe is an ex-NYPD-detective-turned-private eye. Both have their own reasons to hunt down the spree killer known as The Traveler.

His calling cards: the long coat he wears; the masks he leaves at far-flung crime scenes; the online threats he directs at those determined to track him down.

To Bronte and Walshe, The Traveler is a mystery they can solve together. That only they can solve together.
But the killer knows so many things they don't -- especially how the story is going to end. For both of them. For all of them.
Just not yet.
