Gethsemane fought off an attack by a sleazy hotel developer who wanted to turn her Irish cottage into a tourist trap. But now she must face a vengeful ghost determined to exact revenge for a murder that took place centuries ago.
This ghost's wrath spares no one - not Gethsemane's students, Inspector Niall O'Reilly, fellow teacher Frankie Grennan, or the group of ghost hunters that has descended on Dunmullach to capture proof that ghosts exist....
Proof that Gethsemane has to quash to keep Eamon, her resident ghost and friend, from becoming an internet sensation.
As if a spiteful specter wasn't bad enough, a crooked music reviewer turns up dead in the opera-house orchestra pit, a famous composer is arrested for the crime, and Gethsemane must team up with a notorious true-crime author to clear his name.
Because if she doesn't, friends will die, a ghost she cares about will never know peace, and she'll star in a final act gruesome enough for any opera.
