'Today's science fiction so often becomes tomorrow's science fact...' A strange and disconcerting sound like whispering winds and strange rattling and rumblings is filling the air. The wide open space of the Ministry Field is green and overgrown. An old fence and three supporting posts are still sticking up out of the ground. The crumbling, decaying old buildings are now empty, their eerie interiors strewn with rubble and debris, the remains of a place which was once a naval station in the Second World War. Children passing through a hole in a fence and simultaneously vanishing through a hole in the fabric of time, a teenage boy and girl slipping into an invisible Time Bubble where adventure awaits, and anything can happen. These things are the memorable first impressions of the classic 1970s science fiction series Timeslip. Although it is not as famous as Doctor Who or Blake's 7, it is a series which is definitely very notable in the history of British science fiction on television. Looking at the four TV serials, the Look-In dinosaur comic and photo shoot and the Big Finish audio series, this little book is a succinct overview and enthusiastic look at this classic series and its revivals.
