Harry had been trying to find an answer to that for the past week. There was some inevitable frustration tied up in how the case was progressing, feeling like he had been set a decade back, fumbling blindly through the material like a trainee.<br/>He had had to actively remind himself, when he had laid in bed going through what little they even knew, that it wasn’t uncommon for cases to span months, even with his team of three Aurors working the case exclusively. It was entirely normal; besides the fact that Harry was stuck at the Manor indefinitely, adding to the sense of exasperation.<br/>Harry suppressed the urge to rub at his eyes, Malfoy’s wand in the way of the motion. Instead, he picked at his pointer finger.<br/>"We have to figure out a timeframe," he eventually answered. “I’ve been working in this field for a decade, there’s just too many possible occasions I could have encountered dark magic for it to be feasible to find anything if we don’t narrow it down to a time or place.”<br/>Thoughtlessly, Harry’s head had tipped slightly to the left, instinctively tilted away from the movements of Malfoy’s wand. His attention remained on the rough spot on the side of his finger, formed after days of manually writing his correspondence.<br/>"Does the depth of the magic say anything about that? How old it is?"
