The Nursing Home Murder by Ngaio Marsh, 190 pages

When Britain's Home Secretary complained of abdominal pains, it seemed like a simple case of appendicitis. But minutes after his operation, the ill-fated politician lay dead on the table. When Chief Detective-Inspector Roderick Alleyn arrives to dissect the situation, he finds many a likely suspect, including a vengeful surgeon, a lovelorn nurse, an unhappy wife, and a cabinet full of political foes.
