I've never read murder mysteries, so I have no idea how good I'd be at figuring out the plot lines.
Up until I was about 20 I was terrible at picking up on allegory (so terrible that I would always conclude it was BS and couldn't believe that stories contained allegorical metaphors--I just couldn't see it). I have no idea what changed, but I think that nowdays I'm "okay" at picking up on allegory....sub-par, but not absolutely terrible at it.
