This adventure is quite a swashbuckling yarn. The Doctor and Romana are after the fourth segment of the Key, which Romana finds fairly quickly.
Unfortunately she gets waylaid and taken back to Castle Gracht!
The Doctor wants to go fishing but he doesn't get much of it done!
What will happen to them both? Will K9 save the day?
Tune in from 7pm, pressing Play at 7.30pm for a rip roaring, seat of the pants adventure!
