Sulari Gentill sets this mystery-within-a-mystery in motion with a deceptively simple, Dear Hannah, What are you writing? pulling us into the ornate reading room at the Boston Public Library. But fair reader, in every person's story, there is something to hide. The tranquility is shattered by a woman's terrified scream.

While they wait for the all-clear, four strangers, who had happened to sit at the same table, pass the time in conversation and friendships are struck. Each has his or her own reasons for being in the reading room that morning --- it just happens that one is a murderer.

Agatha Christie is the bestselling novelist of all time, and nearly every story she ever wrote involves one --- or, more commonly, several --- dead bodies. And the cause of death, the motives behind violent crimes, the clues that inevitably are left behind, and the people who put the pieces together to solve the mystery invite the reader to analyze the evidence and race to find the answer before the detective does. Christie wouldn't have talked of "forensics" as it is understood today, but in each tale she harnesses the power of human observation, ingenuity and scientific developments of the era. A fascinating, science-based deep dive, THE SCIENCE OF MURDER examines the use of fingerprints, firearms, handwriting, blood spatter analysis, toxicology and more in Christie's beloved works.

Leah and McKenna have never met, though they have parallel lives. They don’t --- ever --- find themselves in the same train carriage or meet accidentally at the gym or the coffee shop.

Leah understands that what’s inside a home can be far more dangerous than what’s outside. So when she notices someone else who may be starting down the same path she’s on, she pays attention. She watches over McKenna from afar. Until one night she sees more than she bargained for.

She’s entrenched in a widespread and nefarious plot involving Will’s employers, and for Will to continue to have any contact with her increasingly fuzzes the line between the people he's working for and the people he’s running from.
