"Not necessarily, perhaps he noticed something amiss through your previous actions," Fafnir turned around and gazed quietly at Angel, "For instance, you were very attentive to the man using the Illusion Technique."
Angel fell silent.
He had once read detective novels written by mortals, where an amazingly perceptive detective, wanting to dissect another person, would take any suspicious action, abnormal behavior, or even the most trivial detail, and use it as a profile for the person in question.
Although Angel had never met Monty himself, from the attitude of the people around him, and the perfectly rounded aura emanating from the masked man and Rhein, which was strikingly similar, it was clear who he was—he was Monty.
And a wizard who could stand at the zenith of the Southern Domain would definitely have more penetrating insight than a mortal detective.
