THE FIRST SEBASTIAN DORRELL ADVENTURE. At Heydn Hall, the ancestral home of the Earls of Newhaven, five people have disappeared mysteriously, including two former earls, an estate manager, and a visiting countess. Why have weird lights been seen in the sky? Why has the Prince's Tower been barricaded? What is the purpose of the strange glass prism on the roof? Has the current earl gone completely crazy? If not, then why has he engaged the services of a psychiatric doctor? And what is really going on down in the cellars? When the Jewish mystic and philosopher, Professor Aaronberg, disappears after writing a book about the disappearances, his friend, sceptical sleuth Sebastian Dorrell, following the dubious advice of a delusional mental patient, begins to investigate.
