A sharp, moving thriller, combining motherhood and espionage, sisterhood and sacrifice. You lose your breath for adrenalin, but also in empathy: for Tessa and Finn, in those quiet nightime moments between mother and son. As tender as it is tense.

A chilling, gorgeously written tale of a modern community poisoned by ancient grievances . . . Berry is a beautiful writer with a sophisticated, nuanced understanding of this most complicated of places.

Thrillingly good . . . Flynn Berry shows a le Carré-like flair for making you wonder what’s really going on at any given moment.

Even at its highest pitch, Ms. Berry’s novel remains a human-centered story that closely examines the behavior of siblings, babies, mothers and friends…a beguiling thriller that’s hard to put down.

Flynn Berry has written a thriller for the ages.

Taut and passionate. . . full of threat and heartbreak. . . Northern Spy will be a hit for readers of Dublin noir and tartan noir. . . Denise Mina and Tana French readers can also find familiar ground – but so in fact can any readers who treasure a well-plotted mystery with a powerful sense of how place and the near past can force a person to cross the lines they once felt were sacred.

Emotional and intellectually engaging
