Killing in C Sharp : a Gethsemane Brown mystery
(Book)

"She saved Carraigfaire-but can she save her friends? Gethsemane Brown fought off an attack by a sleazy hotel developer who wanted to turn her Irish cottage into a tourist trap. Now she must face a vengeful ghost determined to exact revenge for her murder centuries ago. This ghost's wrath spares no one-not Gethsemane's students, Inspector Niall O'Reilly, fellow teacher Frankie Grennan, or a group of ghost hunters descended on Dunmullach to capture proof ghosts exist. Proof 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. 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."--back cover.
