A Country Doctor's Casebook; Tales From the North Woods by Roger A. MacDonald, M.D. The author is a Minnesota doctor who worked in northern Minnesota starting in the 1940s 'til he retired in 1980. This book is stories of his patients, the strange, scary, exciting, and touching adventures he had as a family doctor doing house calls and being on call 24/7. I grew up in a small Minnesota town, and our doctor was very similar.. he made house calls, and I remember him giving me penicillin shots in my butt as I lay sick on our sofa. So as I read this humorous and interesting book, I thought of the family doctor we knew and loved when I was a child.
