The New York Times bestselling and award-winning author returns with a beguiling mystery starring the brilliant, idiosyncratic young sleuth Emma Graham as she attempts to solve a murder, free a wrongfully convicted man—and write her own novel along the way.

THE SWEET CHEAT
by Martha Grimes
Grove Atlantic, December 2026

Twelve-year-old Emma Graham can’t seem to stay out of trouble in the small town of Spirit Lake. But how can she when her small town is besieged by murder, a disappearance, and savage attacks? But nothing will stop her from asking questions and relentlessly pursuing the truth—even if the sheriff is less than enthused.

When two men are accused of murder, Emma dives headfirst into the case, convinced there is a third suspect, a missing piece of the puzzle. Along the way, Emma begins writing her own mystery, inspired by the case and populated by the colorful cast of local waitresses, lawyers, drifters, and kooky customers she encounters during her investigation.

In this original and lively novel, Martha Grimes weaves a propulsive mystery against the backdrop of a vibrant town. Strikingly intuitive, quirky and always curious, Emma Graham is the perfect young sleuth who always sees the best in people—while still uncovering their secrets along the way.

Martha Grimes is the bestselling author of more than thirty books, twenty-six of them featuring Richard Jury, and has sold more than 10 million copies in the US alone. The recipient of the 2012 Mystery Writers of America’s Grand Master Award, Grimes lives in Bethesda, Maryland.
