Death at the President's Lodging - Michael Innes

Death at the President's Lodging by Michael Innes
I have previously blogged about A Connoisseur's Case, which is  no. 20 in the  Sir John Appleby series.
This is the first in the series. It was published in 1936.

The story takes place at St. Anthony's College, where the president is murdered. It is a murder in a confined space and a mixture of  whodunit and howdunit.
The area was locked at night and only 10 persons had a key. That limits the number of suspects. The body was found with a pile of bones  beside it and a gown round its head. The gown belonging to a visiting professor. The involved each try to throw suspicion on his colleagues, so it isn't easy for Appleby to untangle the web.
