About this quote from Harry Potter And The Sorcerer's Stone:
Wednesday night found Hermione and Harry sitting alone in the common room, long after everyone else had gone to bed.
The first clause, in grammatical sense, has the "Wednesday night" as the subject, "found" as the verb, and "Hermione and Harry" as the objects. But I think it's hard (may be wrong) to interpret this sentence in this way.
Does it omit the subject: "Wednesday night (you could) find Hermione and Harry sitting alone in the common room,..."?
