== Publisher's summary ==
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 and advanced early warning network.  
But something goes wrong, and UNIT are 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... and they soon discover worrying connections to both the Fulcrum military training facility... and something beyond this Earth. 
7.2 The Gulf by Tim Foley
The TARDIS lands on an ocean planet and the Doctor and Sarah find themselves on a former rig that’s been converted into an artistic retreat.  
But art is far from the residents’ minds. A painter has disappeared, and the Doctor senses a dark psychic presence at play.  
The waves are rising. And there’s something in the water.

== Notes ==
* This marks the first volume of The Third Doctor Adventures not to feature Katy Manning as Jo Grant.
* Sarah Jane Smith made her debut in The Third Doctor Adventures range, with Elisabeth Sladen's daughter Sadie Miller once again recreating the role, having previously done so in Return of the Cybermen.
* David Richardson teased the changes in store for Volume Seven following the release of Volume Six. He acknowledged that the range had been limited to the Season 8-Season 10 era of Doctor Who, but suggested future box sets would be able to venture into the eras of Season 7 and Season 11. (BFX: Operation: Hellfire)
* With the absence of Katy Manning as Jo, John Levene as John Benton and Richard Franklin as Mike Yates, the volume is also the first to feature no surviving cast members from the original Third Doctor era on television.
