Killer Grandparents

The Asylum Confession Files #10

by Jack Steen

They arrive alive.
They always leave dead.

I am Jack Steen, the night nurse on the death ward of an Asylum for the Criminally Insane. Before my patients die, they give me their final confession—the truth they never told anyone else.

In Killer Grandparents, the confessions come from killers who lived long enough to be trusted. They raised families. They were loved. And they learned how to hide their crimes for decades.

Inside this book are four deathbed confessions from:

Patient Grandma Crystal
Patient Grandpa Herbert
Patient Grandmother(ish) Anna
Patient Grandma Sugar
These killers are expert manipulators. They could be lying to me.

Or maybe they’re telling the truth.

Either way, now they’re talking to you.

WARNING: Contains swearing and disturbing themes. These are the confessions of serial killers and family murderers.

356 pages, Kindle Edition

Are these good?? No. Are they addicting?? Yes. I’ve read every single one of them.

Jack is back and this time round he's speaking to killer grandparents. Not something you really think about is it? Everyone always imagines grandparents to be loving and safe.

The patients are:

Crystal
Herbet
Anna
Grandma Sugar

Each of these stories were completely different and Anna's was just not what I was expecting at all! It actually made me feel really unnerved.

I can understand why Grandma Sugar did what she did, but it was still wrong and should have been handled a different way.

Unfortunately this is my least favourite installment of this series so far. I had to push through to finish, but the final patient's story was fantastic and was a wonderful tale to end on!

Still a huge fan of the series and cannot wait to read the rest!

Wow

Jack Steen's stories are just so good. This book was different than the previous nine because you could almost understand and, dare I say it, empathize with a few of them? I am rating it 4 stars because the first story just didn't do it for me. However, the others were terrific. I hope he never retires lol!

Now I have to admit that I did read the revised version of Crystals story because I was definitely struggling with the book version because it felt like I was just reading someone's stream of thoughts and not an actual well thought out story but the revised version was really good.

Herbert really creeped me out because there wasn't much resolve with his it was he knew how he felt about what he had done and was right for doing it. End of story. Kind of creepy.

Anna's story made my skin crawl because you didn't know who to really blame because the person who actually did the crime wasn't the person Jack was talking to she was just the mastermind behind it. I don't know how I feel about that one.

Grandma Sugar's story gave me that same lower gut pain that Bucket did of who is really the bad guy of this story because she did what she needed to do to stop the the pain and the situation that she was put into but she did still murder a child. I don't know just sits weird with me.

Alas the tenth book is here, I've been waiting patiently for this.

This time around on the chopping block we have killer grandparents! Yes you heard that right, Grandparents.

Our four patients this time are:
* Crystal
* Herbert
* Anna
* Grandma Sugar

Oh and boy do they each have a story to tell! From rules and regulations to using Resin to encase victims. This one has it all!

Damn the first two stories were about control. The third and fourth stories... well Anna was a strange woman but I can see that her and her husband were sad with the children leaving, but what they did with those children hurt my heart. Grandma Sugar on the other hand, I can see why she did what she did. I'm not condoning it but I understand.

Absolutely loved this one, yet again!

Not bad

Favorite story was Anna and Grandma sugar!. The story Anna told did get a little confusing for me cause it kept jumping for the basement to the old burned house. So many questions. Grandma Sugar story was perfection!!

Always good books in this series, but this one felt too subtle. You were left to interpret meaning and scenes that were a lot more vague than the previous books. Almost like every idea or dialogue was Fade-To-Black.

Always a fan of this series

[Tabatha Fetters · Rating 5 out of 5]

😈👀

Not one of his favorites of mine, but I like the writing difference. You can tell the difference between this one and number one, and I'm here for it.
