Dogs (STAGS Series #2) - M A Bennett

After the dramatic events of the last few weeks, Greer Macdonald is trying to concentrate on her A levels. Stuck for a play to direct for her drama exam, she gets help from an unexpected quarter . A priceless lost play, buried by time, is pushed under her door. It is Ben Jonson's The Isle of Dogs, a play considered so dangerous in Elizabethan times that every copy was burned 

... except one.

As the students begin to rehearse, events become increasingly dark and strange, and they lead Greer back to where she never thought she would return - Longcross Hall. There she discovers that not only is the Order of the Stag alive and well, but that a ghost from the past might be too.
