It's hard to imagine that Wormtongue could have been that desperate.

Granted, he'd been ordered apparently to stay out of sight and do his dirty work at night, but surely there was some sort of wretched food he could subsist on. There were the Shirrif-houses, and local Hobbit-holes and houses would have had gardens he could raid.
