Two interesting facts about this cards:

• you're picking up a clue from location but test is not against location shroud value, but it's just (1) (+ number of suspicions)
• you do not perform investigate action, but parley, so if locations can't be investigated (due to some Mythos cards, like Locked Door) you can still pick a clue from it, ignoring obstacle

That being said I think it shines when used in those scenarios: high shroud locations + Mythos obstacles (Locked Door or Obscuring Fog or something else).

Notice that you can take this card with Versatile in Daniela Reyes to trigger her investigator ability pretty reliably, since the attacks from the failed Parley are not attacks of opportunity. And who knows, one time you might even discover a clue by accident.

Another interesting synergie presents itself if you take British Bull Dog with another Versatile, which saves you an action and 3 resources after you fail with Fake Credentials. With discard pile shenanigans offered by the Survivor card pool you can even trigger this combo multiple times per game after British Bull Dog runs out of ammo.

Of course, these are not particularly good plays, but we are here to have fun, aren't we?

(Also, this is my least favorite artwork in the game.)
