The Rainbird Pattern - Victor Canning

The Rainbird Pattern catalogues a search for a highly professional kidnapper: a man who deals in public figures, but makes sure that no publicity attaches to the crime. The result is a secret and fascinating race between the calculating professionals and a bumbling and very unprofessional pair of amateurs, to find the kidnapper.
The book is not, however, a commonplace tale of amateur versus professional sleuth. These amateurs deal in the occult, the search is both on land and in the world of the "spirits". The conclusion is unpredictable and weird. An unusual book for the author and apart from its arbitary and imposed ending, a coldly fascinating experience.
