Denmark is not a land of castles. Perhaps it is too flat. We usually think of castles sitting up on hills or at least hillocks. England has far more spooky medieval edifices. But Denmark has at least one very infamous castle by the name of Kronborg in the town of Helsingor by the sea. It is about one hour from Copenhagen and promises all sorts of spooky adventures to anyone brave enough to enter the doors and visit where Hamlet once roamed and Hamlet’s ghost once haunted the stone walls. Cheops Books LLC will visit Kronborg in the upcoming thriller Murder at Hamlet’s Castle. Hopefully it will sell as many copies as Dan Brown.
