The Blurb for At Death’s Door and the Contents

From the front flap of the dust jacket of the first (and only) edition of At Death’s Door by Leo Bruce, published by Hamish Hamilton (London, 1955):
Leo Bruce has put Sergeant Beef out to grass and introduces us to a new more sophisticated detective, Carolus Deene, with an odious schoolboy assistant, Rupert Priggley.  Deene is an elegant schoolmaster, rather in the Peter Wimsey tradition, rich enough to run a Bentley and an acknowledged and published authority on historical crime.
Leo Bruce’s characterisation is as good as ever, and his dialogue needs to be savoured, for its horrible and perpetually amusing veracity.  Though there are, as usual, satire and comedy, they do not spoil the truly baffling mystery.  The denouement will surprise both the hardened mystery addict and the wildest guesser.
