I think Dirk [Gently] thinks that he's a brilliant detective, but he's the worst detective, ever. He does have this particular skill, which I suppose you might call a really bad superpower because it's just not very helpful. He is able to sense the connections between things and he's nearly always right, but the problem is that he never knows what to do with any of those messages that he receives from the universe, so he just acts on things and gets himself into terrible trouble, all the time.
