Jim Heath
Jim Heath worked in applied
mathematics and engineering. Which led to a writing career. Odd, but it happens. Down the years, he's published books
and long articles that might be a random selection
from Amazon: oil security, dog
psychology, debt collection, email encryption,
bush flies, a beginner's guide to Perth, windmill
disasters, and so on.
But he mainly writes things for others: technical and marketing text for businesses (chiefly websites these days), and ghostwritten non-fiction books.
The free books link includes The Fly in Your Eye, Jim's book about Australian bush flies. The original text, drawings and cartoons. Long out of print, but during fly season it flies on with 3000+ web downloads a day.Mary Heath
