Trouble in Rainbow Valley, a forest paradise in the great Northwest, recalls Clint Gallant from college in order to help his foster father J. C Conley in a competitive struggle with the King Timber Company. Fire sabotage is the overt problem; and what better way to prevent Conley from fulfilling an important timber contract due in 39 days. The villains and heroes take sides as more fires break out, yet Clint cannot believe that John King, the man who offered him a forestry scholarship, is the real demon. Clint's investigations lead to precautionary measures as well as traps -- a fire watch system, a helicopter patrol, etc. But it is Clint's accidental capture that shookingly reveals the unscrupulous traitors in both organizations intent upon usurping Rainbow Valley for their own purposes. Dramatically envisioned, the holocaust of forest fires and the vital importance of conservation techniques come to life in a book geared specifically for the masculine adventurer.
