When a late-summer hurricane slams into Boston, Detective Eddy Harkness and his crew are thrown into the eye of a very different storm. Dark Horse, an especially deadly brand of heroin, is infiltrating the city – and only they can stop it.

Dark Horse, the much-anticipated second novel in the Eddy Harkness series, delivers a whirlwind tale that takes Boston crime into thrilling new territory.

What You See

“Rich in character, riveting in storytelling and fierce in feeling, Dark Horse is both a crackling crime novel and a tough-yet-tender lovesong to a city. With the bruised yet buoyant Eddy Harkness, Rory Flynn has given us a series not to be missed.”

— Megan Abbott
Edgar-award-winning author

The Fever and You Will Know Me

“Sleek, stylish, and bristling with punk-rock attitude, Rory Flynn’s Dark Horse is an utter joy from start to finish. Flynn’s wicked wit, live-wire plot, and knack for creating memorable, nuanced characters is guaranteed to hook. I can’t wait for my next Harkness fix.”

— Chris Holm
Author of The Killing Kind

“Like its hero, punk-rocker-turned-narcotics-cop Eddy Harkness, Dark Horse is gritty, smart, compassionate, and wicked funny. Flynn’s sharp eye for Boston – in sunshine and shadow – is matched only by his deep love of the city and its people.”
