I wish this were a simple matter of a click of the mouse, but it's not.
The Murder of Norman Ware is available on Kindle, but due to some distribution rights you have to have an American billing address (not a South African one) if you want to purchase it.
You can get it on Amazon here. It costs $24.99
You can buy The
Karma Suture and
The Angina Monologues as PDFs for your Kindle through Kalahari, Exclus1ves, and My Books. Use the Jacana links above to get there quickly. Oddly enough, the ebook is somehow more expensive than the paperback copy. Go figure.
