The Fourth Doctor Adventures Series 7: Volume 2 is out now.

7.5 The Shadow of London by Justin Richards
The TARDIS materialises in the backstreets of London in the 1940s. Whilst K9 entertains himself in the time ship's library, the Doctor takes Leela for a walk in the streets.†¨Something strange is happening in the city. Traitors are running wild... and nothing and no-one are quite as they seem. 

7.6 The Bad Penny by Dan Starkey
When turbulence in time takes the TARDIS off course, the Doctor and Leela find themselves visiting a hotel in the middle of a temporal paradox and a terrible plan.†¨Because that’s the thing about the Cross-Keys hotel.†¨You can check in... but you can never leave.

7.7 Kill the Doctor! by Guy Adams
The TARDIS crew arrive on the planet Drummond, an Earth colony in the far future where everybody uses handheld computers from morning to night. Rania Chuma is the mastermind behind Rene.net, the datastream network that tells you everything you need to know. Anyone who’s anyone uses Rene.net.†¨But ever since Rania was young she’s heard a voice in her head. That voice is the key to Rene.net’s success. And it’s a voice the Doctor might find familiar. 

7.8 The Age of Sutekh by Guy Adams
The world has changed. And the evil Osiran Sutekh is returning. A brutal battle is ready to begin. And if the Doctor and his friends fail, everyone in the galaxy will perish.

David Richardson, producer, tells us about making this seventh series, released this year: “While we’re very keen to make stories with the Fourth Doctor as fans remember him, we’re also stepping out into new territories too. We’ve been making The Fourth Doctor Adventures for a few years now, so it was time to shake things up a little while still holding on to all the elements that made them such a success in the first place.”
