THE RACE Detective Isaac Bell returns, in the remarkable new adventure  from the #1 New York Times-bestselling author. It is 1910, the age of flying machines is still in its infancy, and  newspaper publisher Preston Whiteway is offering $50,000 for the first  daring aviator to cross America in less than fifty days. He is even  sponsoring one of the prime candidates-an intrepid woman named  Josephine Frost-and that's where Bell, chief investigator for the Van  Dorn Detective Agency, comes in.Frost's violent-tempered husband has just killed her lover and tried  to kill her, and he is bound to make another attempt. Bell has tangled  with Harry Frost before; he knows that the man has made his millions  leading gangs of thieves, murderers, and thugs in every city across the  country. He also knows that Frost won't be only after his wife, but  after Whiteway as well. And if Bell takes the case . . . Frost will be  after him, too.
