Doctor Who: Death In The Stars
 

A band of killers. Survivors with a secret. A death-defying murder mystery in space.
When young Mel's business partner, Sabalom Glitz embarks on yet another "get rich quick" scheme, it marks the start of an epic, death-defying murder-mystery in space.
After barely escaping the snares of a murderous galactic cult, Mel searches for fellow survivors in a nearby spaceship graveyard - while Glitz looks to fill his pockets. But the discovery of a spaceship with its crew in suspended animation and incredible secrets on board leaves the duo stranded with no way off.
Mel revives the crew - and then the murders start. Murders that cannot possibly have been committed by any of the crewmembers. In fact, there are only two realistic suspects - Glitz and Mel themselves.
