"Everything you want in a murder mystery ...suspense, humor and a twist at the end that you don't see coming."

A gruesome puzzle. A twisted killer. A determined detective. Who will win the game?

Frank, fierce and fearless, Detective Sydney Valentine has never been afraid to ask difficult questions. But when a social worker is found brutally murdered with three Scrabble tiles stuffed in her mouth, she knows the answers will be far from easy to find.

Sydney’s investigation leads her to a disturbing blast from her past: a date-rape predator who attacked her friend Allison at college. Could he be the killer? He got away once before. Maybe now she’ll be able to bring him to justice.

Then more shocking murders reveal more cryptic clues and the puzzle gets harder to untangle. And when the killer turns their attention to those closest to Sydney, solving the mystery is the only way to protect the people she loves.

The murderer is playing a deadly game and Sydney can’t afford to lose. Does she have what it takes to catch this sadistic serial killer? Or will the killer catch her first?

If you’re a fan of police procedural novels with twists and turns that keep you guessing until the very end, you’ll love the Sydney Valentine Mysteries.

​"A real gutsy detective. I couldn't stop reading this book once I started. It is well written, with good twists. Great work! Thank you!"


What Readers Are Saying


I didn't know I needed this until I picked it up by chance. What we have here is - dare I say it? - the best murder mystery novel I've ever read.

Our protagonist - Sydney Valentine - is a young-ish female detective who is not only kick-ass and great at her job, but a really beautifully rounded character, and incredibly relatable. It's not often that a writer will divulge so much family background and non-job-related life and make it work so smoothly with the book as a whole. This writer is breaking stereotypes (except the doughnut-eating-police-officer thing) with every sentence, and I love her for it.

The book is pacy and the case original, but it was the balance between sensitivity and action that really blew me away. Ms Davis writes fantastic relationships; I don't think I've ever been so emotionally invested in crime fiction before! Every character was so human, and every death was treated like a real tragedy rather than a 'complication to the case'.

The plot is a whirlpool of completely unforeseen (or at least, unforeseen by me) twists and turns, and I was completely enraptured by the entire story. I'm still reeling from that ending!

Davis' writing is snappy and gritty; she doesn't shy away from difficult topics, but she never slips into the trap of being overly gruesome. As for the dialogue, there were a few instances where I felt the utterances were too clipped to feel natural, but as a whole it slipped well into the story and read smoothly.

My only question (and please bear in mind this is coming from a young British country-bumpkin) was whether it was true to life to have a network of so many broken and difficult people.

Either way, the layers of humour, profundity and accuracy made this book a brilliant read that I highly recommend. It's an experience I'm so glad I got to enjoy."

Really fantastic! Kept me guessing, trying to figure out who the killer was. I thought I had it figured out but at the end the author threw me a monkey wrench!!!"

“Strong characters, tight plot keeps you guessing until the end. Knowing WHO dunit is a surprise you don't expect or see coming.”

"Sydney is very refreshing and a strong woman who cares about her family and her squad partners. Humor surrounds Sydney's dating life after her sister establishes an online dating profile for her. Female detectives like Sydney are great role models for girls today."

"I am on my third book by this author and love every one of them and can't put them down. I just bought another Sydney Valentine book that is only 15 pages which I normally don't mess with but I love these books. Hate the thought of finishing the third one already. Hope she writes many many more of these. A very talented author."

"I've read a lot of whodunits, but this mystery had me guessing throughout the entire book. I read til 4 a.m. because I couldn't put it down; I just had to know who the murderer was. I didn't figure it out til the very last pages and that's what makes a great story. This is the first time I've read this author and I must say, "Hats off to you, Ms. Davis. I can't wait to read the next book in the series!"

"Gimme a little ASS-KICKING music. Author is a great wordsmith. I like a real BADA$$ protagonist and she gives us one."

I couldn't put it down! The characters were easy to relate to and the story is possible. I would recommend this to everyone.

The Protector is a book about a serial killer who is not only killing people but also attacking law enforcement. Sydney Valentine, the cop on the case, is also trying to protect her family from the killer as well. This story has everything you want in a murder mystery...suspense, humor and a twist at the end that you don't see coming. This book is an easy to read page-turner that won't disappoint. Professionally written. Highly recommended.

Okay...if you love eve dallas, of the JD Robb series, then you will  f$!/=ING love this book!!!! Let me tell you she is like Eve Dallas, on steroids... cannot be happier to have read this book!!!!

This is my first Danielle L. Davis book and she just gained a new fan! I became immersed in the story, constantly trying to figure out who the killer might be and what the scrabble letters, left at each scene, spelled out. The storyline was unique, held my attention so well that I found myself reading well into the wee hours of the morning. The characters were well developed, quirky & interesting. I really liked the sarcasm, side remarks and banter between Detective Valentine and Bernie. After finishing The Protector I can't wait to read more in this series!”

I actually read this book twice, because my first reading was so often interrupted & I thought I must have missed something. I usually can figure out who the killer is, and put the pieces together, but this one surprised me. I want to read the rest of this series.
