Unquiet Grave level 4

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.James, M. R. is the author of 'Unquiet Grave level 4', published 2000 under ISBN 9780194230513 and ISBN 0194230511.
