Obviously a very powerful combination of effects here, but unless I'm mistaken the "then" clause after discovering 2 clues is kind of a big deal. My understanding is that if you can't fulfill the conditions before "then" in full, then the rest doesn't happen.
So in this case it means if you can't discover both clues from your location then they are not automatically evaded, essentially turning into this a testless Followed. That's not awful... but not worth 3xp either most likely. Was thinking this would be huge for Allesandra as it's exactly what she wants, but not being able to rely on the effect to double evade the enemy really hurts.
