The Doctor joins forces with Missing Persons detective Jana Lee to help solve the mystery of a girl who's gone to pieces.

2.2 Fright Motif by Tim Foley

In post-War Paris, musician Artie Berger has lost his mojo, but gained a predator – something that seeps through the cracks of dissonance to devour the unwary.

Luckily for Artie, the Doctor is here. Unluckily for everyone, he needs bait to trap a monster...

2.3 Planet of the End by Timothy X Atack

The Doctor arrives on a mausoleum world for sightseeing and light pedantry, correcting its planetary records. The resident AI has other ideas.

Deep within a tomb, something stirs. Occasus is the last resting place of a species far too dangerous to exist. And the Doctor is its way back.
