In February we go back to the 1970s as Big Finish recreate the years of Doctor Who with the Fourth Doctor and Leela, in the adventure Doctor Who - The Fourth Doctor Adventures - The Darkness of Glass by Justin Richards. Today a spine-tingling trailer has become available on the story's page here.

Cut off from the TARDIS, the Doctor and Leela find themselves stranded on a small island. But they are not alone. It is 1907, and members of the Caversham Society have gathered on the hundredth anniversary of the death of Mannering Caversham, the greatest Magic Lanternist who ever lived.

But Caversham was also a supernaturalist who claimed to have conjured up a demon from the depths of hell. As people start to die, the Doctor begins to wonder if Caversham’s story might have more than a grain of truth in it. Can the Doctor and Leela discover what really happened to Caversham a century ago? And if they do, will they live to tell the tale..?

It's followed by Doctor Who - The Fourth Adventures - Requiem for the Rocket Men in March, and Doctor Who - The Fourth Adventures - Death Match in April.
