By Jill Paton Walsh, dramatised by Neville Teller.
Amateur sleuth Imogen Quy solves another mystery in the academic surroundings of Cambridge University. The locked library of St Agatha's College houses an invaluable collection of 17th-century volumes. It also contains one dead student. Was it a tragic accident, or is there some more mysterious and deadly circumstance surrounding the death of model student Philip Skellow? If anyone can find out it is college nurse Imogen Quy, and her policeman friend Mike.
