I spent eight to nine months in East Africa in 1966. A month in Tanzania; six weeks or so in the Kenya Highlands; the rest of the time in Uganda. Some years later I even used a version of Uganda in a piece of fiction; you can do that only when you feel you have a fair idea of a place, or an idea sufficient for your needs. Forty-two years after that first visit I went back to Uganda. I was hoping to get started there on this book about the nature of African belief, and I thought it would be better to ease myself into my subject in a country I knew or half knew. But I found the place eluding me.
