I bought a copy of this book in 1958. It is now somewhat dilapidated, and yellowed with age. I read it then, as a teenager, and I read it again, a few years later. Then I just kept it.... all these years.
I recently re-visited Capri, where Axel Munthe lived, and wrote this book.
I have just read it again, and even though it is in an unfit condition to pass on to anyone else, pages loose, pages missing (happily, carefully copied in my teenage hand and attached in now yellow sellotape)I would not part wwith this book for anything!
I am sure it is still in print and can be fairly easily obtained, and failing that, the libraries will have a copy somewhere, I'm sure.

This is a story that was first published in 1929, and a best seller world-wide then.
Axel Munthe was more than the "fashionable Paris doctor" of the early 1900's. His stories of the Cholera outbreak in Naples, and the work he did after the earthquake in Messina,and his account of his time in Lapland are riveting.
of all are his stories of his frienships with the animals who adopted him. Billy, the alcoholic ape, for one.

This is a treasure of a story, and well worth the effort to secure a copy.
But not mine, I'm keeping it...you find your own,
but you will not be disappointed!
