A: Yes. To refresh on what those cards do:
Even Death May Die (Action) says “Search through the discard pile. Take any Action or investigator Keeper you wish, and immediately play it. (Anyone may look through the discard pile at any time, but the order of what’s in the pile should not be changed)”
Twist of Fate (Surprise) says “Out of Turn: When another player plays a Keeper, it goes in front of you instead of them, possibly preventing their victory. During your turn: Steal another player’s Keeper and put it in front of you.”
Although it was an Action which precipitated this Keeper being played, and Twist of Fate does not stop Actions, at the point when that Keeper is pulled out of the discard and played… it counts as a Keeper play, and CAN be stopped with Twist Of Fate.
