Winifred seems a very powerful investigator, but you will need a lot of force of will to play with her at the maximum level.
The deck seems solid, but you're are forgetting "Narrow Escape" and "Sneak by", which are always a good choice. I would remove at least one copy of "Opportunist" and "You handle this one" and play one of those (be "Sneak by" my personal choice).
