Reading a book about the Ariel Castro case

Right now I’m reading a book called Captive: One House, Three Women, Ten Years in Hell by Allan Hall. It’s about that notorious Cleveland case, of course. It’s British. I’m 40 pages in and the author hasn’t even begun to discuss the abductions; he keeps talking about Castro’s background instead. Apparently he came from a more or less normal family — I mean, they weren’t perfect, but weren’t horrendous either — and none of this relatives are psychos. The next chapter is going to be about Castro’s horrible maltreatment of his wife.
