Contrary to earlier reports I found him brighter than during our meeting.
I read this sentence in a Google Books library of a author Thorpe Edgar, don't know if he is a native speaker or not. Also I couldn't find answer to this question in those pages which were accessible by Google Books preview but I googled for the sentence and found two results. One says replace brighter than with bright, and the other says it's a No Error sentence, but I think it's not an error free sentence as than (a comparative) has been used in the sentence but the clause/subject/object with which comparison is to be made is not present. So what should be the correction? Replacing brighter than with bright?
