Novel about father, Eric - someone in a routine (8,2,5)

I believe the answer is:

creature of habit

I'm a little stuck... Click here to teach me more about this clue!

'someone in a routine' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'novel about father eric' is the wordplay.
'novel' indicates an anagram (letters in a new or novel order).
'about'+'father'+'eric'='aboutfathereric'
'aboutfathereric' anagrammed gives 'CREATURE OF HABIT'.

Can you help me to learn more?

(Another definition for creature of habit that I've seen is " one who's predictable?".)

I've seen this clue in The Daily Express.
