"Rarely have I seen such a discouraging clinical picture, and I shall certainly have my hands full, all eight of them, with this one.", So says aCrepellian octopod Diagnostician.
To me, the entirety of this book matched the pace, tension and drama of the first chapter of the first title, which is after all what hooked me in the first place.

'"And don’t think you can pull your Senior Physician’s rank on me to get up," she said sweetly as Conway opened his mouth to do just that. "In this instance you are the patient and not the doctor, Doctor."'

Bristling with humour, concern for the mental stability of our protagonist and the well-being of his patients, this installment sees Conway at his very best, the hospital a well-running machine all around him.

Seems to me that this is a perfect end-of-series marker - the characters are all wrapped up and left as neatly as if a season of a television drama was coming to a close. My only slight seed of doubt is that there are more books, and some say the quality declines. This happens with series, of course; but this one at least will certainly stick in my mind for its sheer excellence.
