Oxford Bookworms 4. The Unquiet Grave

If you find a locked room in a lonely inn, don't try to open it, even on a bright sunny day.
If you find a strange whistle hidden among the stones of an old church, don't blow it.
If a mysterious man gives you a piece of paper with strange writing on it, give it back to him at once.
And if you call a dead man from his grave, don't expect to sleep peacefully ever again.
Read these five ghost stories by daylight, and make sure your door is locked.
