Edgar Wallace 
The Black Abbot 

Several employees on a nobleman’s estate show up at a former abbey, reputed to be haunted, to search for a hidden treasure. However, a mysterious hooded figure begins killing off those who may have figured out where the treasure is hidden. Who the Black Abbott is, what his purpose is – and how he is connected with the mystery of the treasure – these are the elements of the story. There’s a malevolent ghost, buried treasure, the elixir of life, a crooked lawyer, a tangled romance, a scheming young woman, another young woman facing a fate much worse than death, an atmosphere of breathless excitement and non-stop Edgar Wallace thrills.
