It's definitely required reading if you're interested in this case, albeit with a critical eye.
IMO he may well be right on keys, or lack thereof, for one thing re: 37. Makes no odds it was/is thought as surely SL was defintley outside and likely with a man. NB: also WJ on fiesta.Other detail too, all builds a piciure. He says, DV, the police agreed with him on pretty much everything bar KH being responsible. So if you read with that in mind... For the police, DV was missing the 'golden thread' that ties some/all of the conjecture around KH/CV together.
