A story by Kate Bold .. the second book in the series about criminal physiologist professor Lucy Crimson.

Lucy has a chance to speak to serial killers that are in jail..
Soon deaths happen with these serial killers ways they go about killing. Someone is copying and there’s body’s stacking up.. Lucy is now on the case

[Deedra Dail-whitley · Rating 5 out of 5]

Great book!! I totally enjoyed it!! I love Professor Lucy Crimson & FBI Special Agent Sam Spears! They're a great team! The books are very well written & keep you on the edge of your seat wondering what the heck they'll get into next!! Even the bad guys, some of them, are somewhat likeable in this book too!! But the ONLY problem is there's even more editorial errors in this book than there were in the first one. Bold's editors need to wake up & do their job cause Bold is banging the books out, so the least they could do is make sure there's no typos?!?!

[Kaylin Evans · Rating 4 out of 5]

3.5 stars, rounded up.
Even though I guessed who the killer was pretty early on, Inside His Heart was still a fast-paced, easy page-turner for me. There was one element of the murders and the serial killer that I didn’t piece together, which made the ending enjoyable. If the book didn’t have so many typos and errors, it easily could’ve been a 4/5.
I really enjoy the plot of these stories, and I like Lucy and Sam as a duo. I find the storytelling and pacing to be strong. We just need the publishers to get it together.

Intriguingly twisted tale of deception

This is a page turner that will keep you guessing right up to the end. And beyond it, for me. It appears our researcher figured it all out, just in the nick of time! I found myself wondering if there was something she might have missed?
A good read, poorly edited, with more than a few misspelled words and names used wrong. It doesn't hurt the story, perhaps only a nitpicker like me would notice. I still recommend this read!

[Susan · Rating 4 out of 5]

I love Kate Bold’s writing! I have read quite a few of her books. This one, however, was easy for me to figure out who the murderer was. They also had a lot of typos in it, calling him /her and totally putting the wrong name on the character in a couple places. It was still a good book with a good plot.

[Maria Hill · Rating 3 out of 5]

I did enjoy this book & yes I agree it could have done with some editing but I felt like I was reading the script for the series “mind hunter” I had to force myself to finish it as I already knew the ending & I don’t like not to complete a book. Overall well written but left me very confused as to how I already knew this book.

[Kyle Tumpak · Rating 3 out of 5]

3.25. Not as good as the first book at first, but things get better way later than I thought they would. I’m not sure if it’s because it’s the kindle version, but there were way too many typos. Also, there were a couple different times that a character would have a completely different last night than before. Kind of distracting, but nonetheless, good book and so far great series.

[Sherry Escobar · Rating 3 out of 5]

Good story

I would have enjoyed the book (as well as her last one) if there hadn't been so many typos and obvious mistakes . I'm sure editing could have been done better by a 10 year old.

[Margaret Kerr · Rating 5 out of 5]

Inside his heart

This book is written to keep you turning possibilities over in your head and hoping your right or wrong as the case may be. I couldn't proofreading it.and I hope that is the same for the next suspense reader.

[Allison Maples · Rating 4 out of 5]

3.5 for me, rounded up for a unique storyline.
While the ending felt a bit rushed, the pacing for the majority of the story was solid and characters were well developed. Definitely worth picking up for a quick read.
This is book 2 in a series, but can also be read as a standalone.

[Mrs MJ · Rating 5 out of 5]

An easy read. Good series.

[Kristy Stephens · Rating 5 out of 5]

I think I liked this one even better than the first!

[Alice Ham · Rating 3 out of 5]

It was a really good book and well written! Have really gotten into this authors books. However, I did guess the killer quite early on but I still thoroughly enjoyed it.

[martina a king · Rating 4 out of 5]

Not bad read

I found this book little less exciting than the 1st book but was still a decent read the killer was easy to spot half way through

[Liza · Rating 3 out of 5]

The murders work but more editing is needed. I will keep reading

[Judy · Rating 4 out of 5]

Lucy Crimson goes to a prison to interview serial killers, then random people are killed like they described!
