“Will leave you dying to know more.” —Rick Riordan, author of the #1 bestselling Percy Jackson series

The New York Times bestselling author of the Peter and the Starcatchers and Kingdom Keepers series, Ridley Pearson, brings us the thrilling conclusion to the Lock and Key trilogy.

Before James Moriarty and his sister Moria enrolled in Baskerville Academy, they were inseparable—as close to best friends as a brother and sister could be. But since setting foot on the boarding school’s campus, James has been different.

At Baskerville, he’s become cunning, deceptive, ruthless, sometimes reckless. And now that his roommate Sherlock Holmes has been expelled, there’s no one left to help Moira figure out what’s going on with her brother or to uncover the connection between a recent string of deaths.

To Moria, it seems obvious that someone has it out for the Moriarty family. First their father and then their family driver and now their legal guardian—clearly something is afoot. But to get the answers they need, they’ll first have to deal with an incriminating photograph, secret safe houses, and powerful enemies.

It’s a highly original and satisfying take on the Sherlock Holmes series as only master of suspense Ridley Pearson could envision. As Rick Riordan, author of the Percy Jackson series, says, “This tale will change the way you see Sherlock Holmes and leave you dying to know more.”

At the thrilling conclusion to book one, we left off with James and Moira’s father dying horribly and unexpectedly. Now the search is on to find out what really happened to their father. Did he fall or was he pushed? Sherlock, James, and Moira reluctantly partner up, trusting no one, not even each other, as they uncover a secret sect, a rare jewel, and a sordid history. Blood is spilled, trusts broken, and friendships lost in this story of how one simple mistake cost Father his life and James his heart, and sent the Moriartys spiraling ever downward.

It’s a highly original and satisfying take on the Sherlock Holmes series as only master of suspense Ridley Pearson could envision. As Rick Riordan, author of the Percy Jackson series, says, “This tale will change the way you see Sherlock Holmes and leave you dying to know more.”

A riveting tale about the origins of the rivalry of literature’s most famous enemies—Sherlock Holmes and James Moriarty, told from the perspective of James’s observant little sister, Moria.

Before James grew up to be a ruthless, remorseless villain, he was a curious boy from Boston, with a penchant for trouble and an acid tongue. Thrown into a boarding school against his wishes, James winds up rooming with a most unlikely companion: a lanky British know-it-all named Sherlock Holmes (“Lock” to his friends). An heirloom Bible, donated by the Moriarty family more than a hundred years ago, has gone missing, and it doesn’t take long for the two to find themselves embroiled in the school-wide scandal.

The school is on lockdown until it’s found, strange clues keep finding their way to James, and a secret society lurks behind it all. It’s a brave new reimagining of the Sherlock Holmes series as only master of suspense Ridley Pearson could envision. As Rick Riordan, author of the Percy Jackson series says, “This tale will change the way you see Sherlock Holmes and leave you dying to know more.”
