The Ghouls Of Calle Goya by Owen Jones

Londoner Frank marries Joy, a beautiful young Thai, who works in town. She has always dreamed of going to the Costa del Sol, so they head to an apartment in Fuengirola loaned by Frank’s boss for their dream honeymoon.
Things start to go wrong when Joy fears that the apartment is haunted. Fear leads to depression and deepens into terror. Frank has no idea what to do, except take her back to her family in Thailand, but that brings its own misfortune.
Life finally looks brighter because of the intervention of a secret Scandinavian society.
This is the story of how Evil can result from good intentions. It is a fantasy, but based on true events.
