Review of Deadly Animals by Marie Tierney

As the first chapter of this contained a lot of decomposing animals, I continued reading with some trepidation.
But I was completely enthralled by main character Ava Bonney, a peculiar fourteen year-old with a fascination with death. When she stumbles on a dead human body, she anonymously reports it to the police (so they won’t find her collection of road kill.)
Enter DS Seth Delahaye, a detective investigating the disappearance of a local boy and a suspicion that Ava knows more than she’s saying.
I don’t know if it was just me, but
I felt that the book was hinting pretty hard at who the killer was.
That doesn’t always bother me, as a) I might be wrong (I wasn’t) and b) that can set up a cat and mouse dynamic that can be very suspenseful.
Overall, I really enjoyed the 1980s feel of this in both setting and topic.

I agree with a lot of what you said. I thought Ava was a great main character and I enjoyed the book leaning into the macabre.

But I thought the killer was very obvious – so obvious that I was curious if there was an actual twist. Even early on there was the poem about the killer’s eyes, then a discussion about N’s eyes in the next scene. The police talked about the killer wearing gloves, then Ava took N’s gloves. Same with N’s strength, the bike as transport, the glasses, the head injury, the lack of discussion about N’s family, the roadkill, the hints of abuse.
I’m wondering if the point is to be looking in, watching to see when the characters figure out what is obvious to the reader (and if they do so in time to avoid further deaths!).
I agree with you! At first I was convinced he had to be a red herring as the clues were so strong. And yes, I do think that sometimes when we know (or suspect) who the killer is, it makes the book all the more suspenseful!
