314 pages; ex-library with usual markings, edge wear, spine creasing; A soft-hearted sleuth with a rebellious streak left over from the '60s, Leo Waterman seems to get entangled in every oddball situation. So when he's hired to locate Caroline Nobel, an errant mob heiress and landscape-loving activist, Leo goes with the flow and follows her into the rain-soaked Washington woods. But Caroline's conscientious cohorts are dragging her deeper into the murky waters of environmental sabotage. And her hot-headed enthusiasm can't be cooled, even after two people are brutally murdered. She's onto something extremely toxic. And unless Waterman can clear the air, her deadly dedication could poison him as well . .
