Doctor Who is strangely concerned about Professor Horner's plan to cut open an ancient barrow near the peaceful English village of Devil's End; equally worried is Miss Hawthorne, the local white witch, who foretells a terrible disaster if he goes ahead; determined that the Professor should is Mr. Magister, the new vicar (in truth the Master) whose secret ceremonies are designed to conjure up from out of the barrow a horribly powerful being from a far-off planet... The Brigadier and Jo Grant assist Doctor Who in this exciting confrontation with the forces of black magic!

Novelization of the Doctor Who TV series; five episode story "The Daemons" (1971), script by Barry Letts and Robert Sloman.
