If you need a good business thriller to keep your mind off the stock market, you can"t do much better than this one from Stephen Frey, former Wall Street insider and author of two previous barn burners, The Takeover and The Vulture Fund, both available in paperback. The Inner Sanctum pits smart, ambitious, underpaid IRS agent Jesse Hayes against smart, ambitious, overpaid portfolio fund manager David Mitchell in a story about corporate greed and political corruption that reads like a cover of Time or Newsweek.
