Take things quietly (5)

I believe the answer is:

steal

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

'take' is the definition.
(I know that steal is a more specific form of the action take)

I cannot understand how the rest of the clue works.

(Other definitions for steal that I've seen before include "Pilfer" , "Creep" , "Walk off with" , "Plagiarise" , "Rob" .)

I've seen this clue in the Evening Standard.
