in the previous book return of the werewolf, margaret gunn was raped by werewolf tom owen, and in the beginning of this book, she gives birth to a werewolf of her own. he grows up, kills a school teacher, gets sent to prison, and discovers his lycanthropic powers while he is there.
as a nice change of pace, this book isn,t completely set in the country like the previous 2, as it does spend some time in birmingham. the mysterious black dogs, only mentioned in the previous novels, actually make an apperance in this one. journalist gordon hall returns once again when he is called in by margatret gunn to sort out the problem of her wayward son.
i don,t think there was any need to include the black dogs in this book. they supposedly turn up because of the werewolf, but since they never showed up in the previous 2 books, their inclusion here makes no sense. the body count is much higher this time, so i guess thats 1 point in its favour
