I asked Kade’s mum if she could put me on the visitation list to see Tobias, and tomorrow morning, I’ll be sitting down with him – the psychopath I used to study religiously. Every article, every documentary, even the leaked interview with him from the day he was arrested – I poured over it all, fascinated by his mind and the way it worked; the way his eyes, devoid of anything, darkened whenever Aria Miller was mentioned.
