The Killer Inside

I'm super happy I found a new series to read! I have a huge addiction to thrillers and this one was just up my ally it is included in the kindle unlimited subscription and is definitely worth the time.
The Killer Inside features Detective Sergeant Jessica Daniel. She has recently received a promotion after her superior was stabbed and left the force. Soon after, she is called to investigate a murder. A woman has been found dead in her home but without any signs of a break-in. It's disconcerting when all the windows and the doors are found to be locked. The police had to break in the door to get in. Sadly, no one in the neighborhood has seen anything important. When another body is found dead in a similar way as the first victim and no door or windows are unlocked, Jessica starts to suspect she is dealing with a serial killer. Of course, it doesn't help when someone from the police station starts leaking information to the press and her superior believes it could be Jessica. To make matters even more stressful for her, her roommate and best friend seem to have found a guy she wants to keep and the closer their relationship becomes, the more uncomfortable Jessica is around them. She doesn't like to be the third wheel.
I enjoyed the whole story. I liked Jessica a lot. She was determined to find out the truth about the murders and give the families some peace. She was smart enough to connect the dots and figured out more than anyone else what was making the killer tick. She had a good working relationship with the rest of the police staff too.
I was surprised at how much I ended up liking her with Garry. I loved the way she tortured him about his jacket. Every interaction they had after the first time they met had a funny element.
I want to see more of them together in the next book.
