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

'false front?' is the definition.
(I've seen this in another clue)

(Other definitions for guise that I've seen before include "Demeanour" , "General appearance" , "Shape; pretence" , "Appearance, semblance" , "Show" .)

I've seen this clue in The Times.
