Can anyone tell me the title of this book?

I once read an interesting book by Derek Humphrey called JEAN'S WAY. It recounts the author's experience with assisted suicide. Some years later, the author's second wife (or partner) writes a book where she recounts the black side of assisted suicide. Can anyone tell me the title of this book? I gave this book away and now would like so much to get hold of another copy. Thank you.
