So is this the code?

use doctorwho

Select authorname

from tblauthor as a
inner join tblepisode as epi
on a.authorid = epi.authorid

inner join tblepisodeenemy as ene
on epi.episodeid = ene.episodeenemyid

inner join  tblenemy as enemy
on enemy.enemyid = ene.episodeenemyid

where title like '%Daleks%'
