Two brand new adventures for the Third Doctor, Liz Shaw and Sarah Jane Smith:

7.1 The Unzal Incursion by Mark Wright

Under the supervision of the Doctor, the Brigadier and Dr Liz Shaw, UNIT are getting ready to activate Hotspur: their new, advanced early warning system.

But something goes wrong. Can it be that UNIT has been betrayed from within? Suddenly bases are falling across the globe, and only the Doctor and his friends are able to escape.

Not knowing how far the conspiracy goes, the Doctor, Liz and the Brigadier become fugitives. Their investigations lead them to the Fulcrum military training facility. And something beyond the Earth.

7.2 The Gulf by Tim Foley

The TARDIS lands on an ocean planet where the Doctor and Sarah find themselves stranded on a former rig, which has recently been converted into an artistic retreat.

But art is far from the residents’ minds. A troubled member of their collective has disappeared, and the Doctor senses a sinister psychic presence. The waves are rising. And there’s something in the water.
