While I agree in principle that fiction writers should avoid the passive voice and choose a strong verb in instead of resorting to adverbs, the passive voice and adverbs are functional part of the English language, and I use them when required by the shade of the narrative. I take my example from Evelyn Waugh who, it was said, never wrote a bad sentence. Take this sentence in Decline and Fall (chapter 9 about sports day). There were accusations of cheating:

No one spoke of the race, but outraged sportsmanship glinted perilously in every eye.

Would Waugh’s meaning be the same – have the same force – if one removed ‘perilously’ ? Or what verb could replace the already descriptive ‘glinted’ and convey the same meaning?
