Stella Knox #13
Killer Plot
Their fate isn’t carved in stone. It’s written in blood.
Three months ago, Special Agent Stella Knox finally took down the man she’s spent her entire career chasing—the man responsible for her father’s death. Now she and Special Agent Hagen Yates are enjoying a well-deserved leave of absence in a secluded cabin in rural Pennsylvania, where the snow falls heavy, the fire crackles, and the silence feels almost too perfect.
Until they discover a body.
Hanging upside down from a tree in the icy woods, a psychiatric patient from the nearby hospital has been ritualistically killed—his throat slit, his blood drained, and cryptic symbols carved with chilling precision into his flesh. The word written in the ancient language of gods and demons portends what’s to come.
Death.
The storm trapping them in this isolated town is no longer their greatest threat. With a killer hiding in their midst, Stella’s instincts tell her the hospital holds answers—but are they unraveling a murderer’s motives or awakening something far darker? In a town suffocating under snow and terror, the line between sanity and madness blurs, and no one is safe from what’s coming next.
Brace yourself for the shocking twists and unrelenting suspense of Killer Plot, the thirteenth pulse-pounding installment in the Stella Knox Series by bestselling authors Mary Stone and Stacy O’Hare.

KILLER PLOT is the thirteenth installment in the Stella Knox FBI Mystery Series by Mary Stone and Stacy O’Hare. These authors never disappoint in bringing us a chilling thriller with a twisted and gruesome plot. As usual, Mary and Stacy have outdone themselves in this page turning story full of drama, suspense, and surprises.
Stella and Hagen finally helped 'Uncle Joel' Ramirez (the murderer of their fathers) to leave this world. Now they are taking some much needed time off together. Their two month idyllic vacation in the mountains is coming to an end when their help is requested in searching for a missing patient from the local mental hospital. Their search ends up investigating ritual murders with blizzard conditions hiding any clues.
Right to the end, the killer is well hidden within the many twists and turns. You're sure to get lost while while sitting on the edge of your seat. As usual, the ending is a setup for the next book, leaving you intrigued and waiting
If you enjoy a good thriller, I highly recommend this series. You will find it hard to say no to a book from Mary and Stacy. I did receive a copy of this book from the authors and this is my honest and freely given review.

Stella and Hagen are enjoying the tail end of their time away from work after taking down the man and organization responsible for their fathers' deaths. When the deputy of the small town where they are vacationing asks them to help in the search of a patient from a local psychiatric hospital, their vacation ends and they are on the hunt for a murderer who leaves weird marking the backs of the victims and drains them of their blood. And all of this is taking place during a whiteout blizzard! Well written and definitely a stay-up-late type of book. And the ending leads the reader to believe it is not all over!!

Stella and Hagen are away from the job to rest and recuperate for a while. They have found a cabin to rent that is away from all the crime and death that is part of their life these days. They have started planning their return to the city and back to work. However those plans are interrupted when a patient from the local hospital cannot be found. They organize a search but are hindered by the large snow storm headed right for them. When the patient is found it is a grizzly scene, and the many lies told by the town folks complicates matters more. You’ll not want to put this book down.

Here they are in a cabin in the mountains of Pennsylvania. It's a small town of just about 1,000 people. And, a murderer! Stella and Hagen have taken a well-earned break but just about the time their vacation is due to end a patient from the local mental hospital is missing. They do their duty and join the search and what they find sends this town into a murder capital. Lots of turns in this book and you can fall down a rabbit hole if you miss certain clues. I like Stella and Hagen they are a good team. The ending is a setup for more books and it's very intriguing. Good read.

Quite the change of location for Special Agents Stella Knox and Hagen Yates. From Nashville to the snowy woods of PA. This is where the agents are enjoying their vacation. The mystery that Mary Stone and Stacy O’Hare have created is captivating. As a reader nothing like sitting in a cozy chair while the story unfolds with blizzard conditions! Lots of twists and turns and unexpected surprises. The authors kept the killer well hidden until the end. So good, cannot wait for the next in this series!

My favorite of all of Marys series. She and Stacy have done an excellent job. Read the book straight thru, could not put it down. Stella and Hagen are awesome characters and it has been fun watching their relationships develop. With everything they have been thru you want them to have their happily ever after. The case left us guessing to to very end.
Can't wait to see what happens in the next book and hope for many More

Killer Plot( Stella Knox FBI Mystery Series Book 13)
This book was so worth the wait, it had so many twists and turns in it. There is a murderer in a very small town and they have a sadistic, ritualistic way of marking the bodies. You don't really figure out who is doing the killing until the end, but they also leave questions left to explain. I can't wait for the next book.

Odd Killing
The story was very good. Understanding why the FBI agents were up in Pennsylvania because of their last assignment and the need for a vacation helped understanding the need for the small town needed their help. Finding the first murder and trying to understand it was difficult. It wasn't until the ending that the one doing the killing was discovered.

Story was ok
The storyline was ok, if you could overlook all the obvious grammatical errors. All The misspelled words throughout the whole book and all the double words and misspelled words in 1 sentence that I couldn't understand.

Off the beaten path
This one caught me by surprise. I followed it but could not connect the dots, which is perfect for me! Fighting crime in a small town should be a piece of cake, especially for 2 FBI people but it kept them, and me, on the edge of my seat

Not only is this a cliffhanger on what Stella will do, it’s also one as to whether they truly caught the killer(s). Also what about the poor dog
