Doctor Who: The Forgotten — IDW Publishing
Issue: #4
On the run from angry spiders and a shadowed, bearded enemy, the Doctor remembers a Sixth Doctor and Peri tale, as well as a Seventh Doctor and Ace story! But neither of these memories are enough to help him. They need to find a Gallifreyan time ring, displayed somewhere in the museum. But Gallifrey no longer exists! And why is a Cloister Bell ringing?
