In the Galactic Census, idyllic Strellin is recorded as a Grade Three
planet – its inhabitants possessing neither advanced technology, nor
knowledge of other worlds. Accordingly, Strellin is protected: landings
by off-worlders are strictly prohibited. Unless, of course, those
off-worlders are officials of the Galactic Census itself, come to
investigate the origin of a mysterious sub-space signal – a signal no
native of Strellin should be able to send...
Breaking all local by-laws, the time-travelling Doctor and his
companion L/Wren Mrs Constance Clarke (AWOL) have only just landed on
Strellin, too. But they and the Census officials aren't the only
off-worlders to have come here. Inside a nearby monastery, the monks of
the reclusive Brotherhood of the Black Petal are guarding a strange and
terrible secret. Something that might bring disaster not just to
Strellin, but to every civilised world in the galaxy!
