The trailer for Lady Christina has been released – hold on for the ride of a lifetime...

1. It Takes a Thief by John Dorney

The French Riviera has always provided rich pickings for the aristocratic cat-burglar. Lady Christina is enjoying the high life while adding to her collection.

But when suspicion falls on her after a robbery-turned-murder, Christina decides to catch the culprit herself…

2. Skin Deep by James Goss

Sylvia Noble always knew she deserved better. So, when a chance encounter with aristocracy propels her out of Chiswick and into high society, she’s delighted.

But the beautiful people have their own agenda – and Christina is surprised when those plans involve her father.

3. Portrait of a Lady by Tim Dawson

When her plot to steal a priceless painting runs into trouble, Christina crashes into an undercover UNIT operation – and Sam Bishop.

Soon, her Number 200 bus is racing from Europe to South America and into the depths of the Pacific, chasing a mysterious and unstoppable foe…

4. Death on the Mile by Donald McLeary

Lady Christina has been offered a job: the heist of a lifetime. She simply has to break into Edinburgh Castle. At the same time, UNIT are investigating alien activity at the Military Tattoo.

And where there’s treasure and treachery, there are also Slitheen….

Michelle Ryan was thrilled to return to the role of Lady Christina: “Being asked to revisit the role was a very easy decision. Adventure, a sunny climate and mind-boggling scenarios are included in the scripts, everything I remember of my Doctor Who experience. Alas no David Tennant, but there’s a host of new characters to help along the way.

“I love that we get to see a little more of her heart in these stories, that she does care about the greater good whilst also satisfying her curiosity for life.”
