This is to Investigation what Improvised Weapon is certainly not to combat.
A -1 on investigate checks is largely equivalent to a +1, and +1's on investigating tend to be regularly useful, moreso then fighting since failed investigate checks rarely have the same repercussions as failed fights.
The kicker is the + 1 clue, this mechanic is so very hard to come by, multi-clue pickup is rare and powerful, and the audience that has access to this card will appreciate it! Wendy Adams can drop the card initially for her ability and just cash in for the clue benefit. The other dudes, despite their lower stats, can still play this card on 1 difficulty locations to trick up clues just as they would with "Look what I found!". Out of faction Minh Thi Phan can play this alongside Deduction to hit impressive clue gathering speed and Finn Edwards might even give it some though.
Wendy Adams and Finn Edwards can even combo Winging It with Double or Nothing to net 4 clues!!
Unlike Improvised Weapon where the first play of the card is rather iffy, there is actually an extra bit of usefulness for this card, you can lower a 3 difficulty location to 2 difficulty, putting it into the "Look what I found!" combo sweetspot like a Flashlight would. This greatly extends a character's ability to gather clues, especially if said character has their hands full with a Baseball Bat, Ornate Bow or the like.
Is this card better then Deduction? Probably not, but it's good for what it's made to do, surprisingly flexible, and a fresh source of multi-clue gathering.
