In modern-day London, two brilliant high school students—one Sherlock Holmes and a Miss James “Mori” Moriarty—meet. A murder will bring them together. The truth very well might drive them apart.

Before they were mortal enemies, they were much more…

FACT: Someone has been murdered in London’s Regent’s Park. The police have no leads.

FACT: Miss James “Mori” Moriarty and Sherlock “Lock” Holmes should be hitting the books on a school night. Instead, they are out crashing a crime scene.

FACT: Lock has challenged Mori to solve the case before he does. Challenge accepted.

FACT: Despite agreeing to Lock’s one rule—they must share every clue with each other—Mori is keeping secrets.

OBSERVATION: Sometimes you can’t trust the people closest to you with matters of the heart. And after this case, Mori may never trust Lock again.

This book never had much appeal to me from the go-get. My mother happened across it and decided to buy me a copy. Being an ‘ungrateful teenager’, I had thanked her and almost forgotten about it. But for some reason, my curiosity spiked and I began to read the novel.

I wore a hat with a feathered plume the first time I met Sherlock Holmes.

Admittedly, upon reading the first line of the Lock & Mori, I panicked. Despite having nearly eighteen years on this earth, I have never once even touched a book by Arthur Conan Doyle. (Pitiful, I’m aware.) Not even BBC adaptations involving Benedict Cumberbatch or movie adaptations starring Robert Downey Jr (I think) had enticed me. So I was slightly unaware of the whole running of the show around the Sherlock series and ever-growing fandom.

So I leaned enticingly close to Sherlock Holmes, so close that I noticed how the blue of his eyes was the exact same shade as my own.”

However, my Wattpad reading days have provided me with sufficient evidence to believe that usually Sherlock books involving romance are usually based around Sherlock and Watson, rather than Sherlock and Moriaty. Still, I gave the book a chance and began to read to see if it would peak my curiosity.

“Sherlock shrugged. “I don’t understand the need for power, really. There are more important pursuits.”
“Only those who have never felt powerless can afford to think like you.”

The book as a whole was amazing. As a young adult reader, this type of novel is the stab in the arm modern day writing needs. The thrill of the chase (both romantically and criminally) and the mystery of murder was woven into the seams of the book. The themes of domestic violence and romance juxtaposed, but somehow managed to compliment one another. I adored how when Mori needed someone to save her from her father, Lock was there. I won’t lie, I’m a hopeless romantic. And so the idea of two teens who both seem like complete outcasts, falling in love while trying to uncover a murder mystery was a genius idea.

“When a person cares for another, he wants to know everything about her all at once.”

Essentially, the characters were fantabulous. Honestly, even though that isn’t a word, it should be. Sherlock was mysterious, logical, cool. Moriaty was secretive, a puzzle of her own and damaged. The writing of the book seemed flawless. Not once did I find myself looking to see when the end was. Instead I was too busying fan-girling over the romance Lock and Mori shared, and mourning over the true reveal of the killer.

“Maybe that’s how one becomes a killer. Not with decision, but with acceptance.”

I refuse to ruin the book for another person. The ending will not be spoken from my lips. However, while I was slightly disappointed, I was ultimately pleased that this may be one of many books. Heather W. Petty did a great job, and I honestly cannot wait for the second instalment. 4 out of 5 snowflakes.

4 stars
