Blackwood Tapes Books in Order

The Blackwood Tapes series begins like a straight thriller and then veers into something older and stranger. At its center is FBI agent Odessa Hardwicke, a young investigator whose career is derailed when she is forced to shoot her own partner during what should have been a routine arrest.

In The Hollow Ones, Odessa sees a shadowy presence slip out of her partner’s body at the moment of death. No report form can hold that detail, and no supervisor wants to hear it, so she is shuffled onto busywork in a field office. While cleaning out a retired agent’s files she discovers references to Hugo Blackwood, an elusive consultant who has been turning up in case notes for over a century without ever seeming to age.

Blackwood calls himself an investigator, not a magician. He arrives in tailored clothes, speaks in a careful old fashioned way, and comes with a long history of taking on crimes that never make the news. What he hunts are Hollow Ones, incorporeal entities that ride human beings like vehicles, pushing them toward acts of violence and ecstasy before moving on to the next host.

Part of the fun of the series is watching Odessa try to reconcile that idea with the world she knows. She has been trained to trust physical evidence and chain of custody, not whispers about Mesopotamian cults or haunted objects. Each time a new atrocity breaks out, she can see the human motives at work, yet Blackwood insists there is another will, older than any of them, standing just outside the visible frame.

The books move back and forth in time, threading Odessa’s investigation together with earlier episodes from Blackwood’s long life. One chapter might unfold in 1960s Mississippi, another in pre war Europe, another in modern New York. The tapes and files that give the series its name feel like a patchwork archive, a set of warnings left for anyone stubborn enough to listen.

That structure lets Guillermo del Toro and Chuck Hogan mix flavors. There are sequences that read like classic occult detective stories, with seances, cursed artifacts, and half remembered rituals. Others are closer to police procedural or conspiracy thriller, where the supernatural threat hides behind familiar systems, from local sheriffs to federal agencies.

Taken together, The Blackwood Tapes has the mood of a case file that never fully closes. Each victory costs something, and each solution hints at a deeper layer of the problem. Readers who enjoy slow burn horror threaded through investigation and history will find a lot to follow in Odessa and Blackwood’s uneasy partnership.
