The Blurb for Death on Romney Marsh

From the front flap of the dust jacket of the first edition of Death on Romney Marsh by Leo Bruce, published by W. H. Allen (London, 1968):
A gossipy aunt, a lady of strong convictions and fearless opinions, sets Carolus Deene off on a trail of investigations leading back to a murder committed twenty years earlier.  The actions of an unfriendly ex-army captain, living in a gloomy old house with an eccentric wife and an aged butler, seem to lend credence to the aunt’s story.  A series of strange incidents finally convince Carolus that someone wants him out of the way..
His investigations lead him into some very odd places, including a search in a crumbling family mausoleum, which reveals a truly extraordinary situation.  Fortunately, Carolus’s acute sense of perception warns him of the great danger he is in personally—a warning which, for all his precautions, is soon translated into horrible fact.
