Appleby And The Ospreys (35) (Inspector Appleby)

Clusters, a great country house, is troubled by bats, as Lord and Lady Osprey complain to their guests, who include first rate detective, Sir John Appleby. In the matter of bats, Appleby is indifferent, but he is soon faced with a real challenge - the murder of Lord Osprey, stabbed with an ornate dagger in the library.
