Quotes & Sayings About Scottish Countryside

More of a QUESTION: When I was in high school in the 1980's I read a book but cannot remember the name. It had a spooky green cover with a german shepherd like dog on it and I seem to remember it being about ghosts or something in the English countryside -although it could have been Irish or Wales or Scottish. Does anyone else remember this book and can you tell me the name? I would love to reread it since it set me on my path to my LOVE if reading. — M.D. Robinson

George had sent him a handful of postcards over the last two months. The front of each of them had borne a photograph of the idyllic Scottish countryside. And on the back, a series of messages circling a single theme:

So bored.
Kill me now.
Too late, already dead. — Cassandra Clare
