The clock is ticking as Nina and Chris race to solve the phantom's mysterious clues. But they aren't the only ones seeking the valuable bounty. Can they manage to find it first?   The Ghost Wore Gray is the second book of the Nina Tanleven Mysteries, which begin with The Ghost in the Third Row and continue with The Ghost in the Big Brass Bed.   This ebook features an illustrated personal history of Bruce Coville including rare images from the author's collection.
