Obsessed with True Crime discussion

The shelf for Atlanta Child Murders has a lot of books that look interesting. I'm looking for one that explores other possible suspects. I definitely think Wayne Williams committed most of them, but I also trust John Douglas when he says "It isn't a single offender and the truth isn't pleasant."

So, I'm just wondering if any of the books on the shelf (or perhaps some that didn't make the shelf) delve further into what Douglas might have been referencing.

Books that discuss the topic, but aren't dedicated to it, are OK as well. I have read Mindhunter. Bonus points if I can get it on Audible.

Dettlinger and Prugh explore a lot of possibilities and make a lot of good points about the multiple-offender idea in The List.

The List is by far the best book on the case, I just wish it wasn't so expensive, as it is long out-of-print and there aren't many books on the case.
