Deadly drifts

the long version

"Macduff Brooks wants to return to his earlier existence as Florida law professor Maxwell Hunt. Depressed after his wife El died in a terrifying boating accident on the Snake River in Wyoming, Hunt increasingly accepted 'special work' for a federal agency. He was nearly killed in Guatemala and reported as having died of a stroke. He was placed in a federal protection program with a new identity as a fly fishing guide and a new home in Montana.
