Low German novel is something to entice a swimmer (9)

I believe the answer is:

angleworm

'something to entice a swimmer' is the definition.
(angleworms are used as bait to entice fish)

'low german novel' is the wordplay.
'novel' is an anagram indicator (letters in a new or novel order).
'low'+'german'='lowgerman'
'lowgerman' anagrammed gives 'ANGLEWORM'.

'is' is the link.

(Another definition for angleworm that I've seen is " Fisherman's bait; meal grown (anag.)".)

I've seen this clue in The Guardian.
