I want to correct the following sentence so that it is grammatically correct and still conveys the original meaning:
Many alcoholics attempt to conceal their problem from their fellow workers, but invariably failing to keep their secret.
The bold-faced part of this sentence is where the error occurs.
It would be great if you guys could help me decide between these two choices.:
- but they invariably fail to keep their secret.
- but fail, invariably, to keep their secret.
1 is good but lacks parallelism and is not as succinct (short and clear) as 2.
But the problem with 2 is its awkward adverb placement that might affect the original meaning.
