His best book, since Hatter's Castle. Cronin is a doctor himself, and this book, the experiences of a young doctor working his way up from medical school to success as a fashionable London physician, has doubtless a basis of sound knowledge of the problems sincere young idealists face. The early part -- his struggles against prejudice and jealousy and superstition in the mining districts of South Wales, were to me the most interesting parts of the book. With ultimate success came the dangers of too much money, power and adulation -- and too little challenge to his real abilities, and for a time he succumbed, putting not only his professional standing but his personal ambitions, ideals and happiness in peril. Just in time, he realized where he was heading, in time for his honor as physician, not in time to rescue his happiness as a man. A grand story, well told, and better balanced than anything else he has done.
