The Private Patient by PD James
A muckraking reporter with a terrible scar from childhood and more enemies than she knows checks into a private clinic for plastic surgery is murdered after the completion of the tricky procedure, leaving it up to Commander Adam Dalgliesh and his murder squad to find the culprit. The squad is called into what should be an ordinary case in the country by a politically well connected patient, much to their unhappiness, as each member of the squad had pressing personal business in London. Not the least of which is Adam Dalgliesh, poet-policeman who is finally ready to wed his beloved Emma. Yet, he must take to Dorsett to find the killer once again.
James has once again created a stellar crime novel that will rival any in the genre. Her characters are always rich and complex, unlike the cutouts found in a lot of the muck that passes for crime novels. I personally adore the way she presents the mysteries and the characters inside their world, making the Dalgliesh books one of my favorite fiction escapes, sitting side by side with the Rebus books by Rankin and anything by Michael Connelly. Dalgliesh should be well suited for many more cases, as long as the good lady continues to write.
