"A fast paced thriller-cum-horror-cum-snarky-dark-comedy with two of the most interesting protagonists I've ever encountered."

Victorian London's most incompetent crooks - turned demon hunters - are back.

When Tess Marchant gets a plea for help from an old childhood friend, The Great Big Demon Hunting Agency finds itself heading out to the countryside, to solve a mystery involving a Manor House and its wealthy family cursed by a malevolent demon.

Spencer and Bart find themselves in a world totally unfamiliar to them: of landed gentry, fearful poachers, and strange creatures which stalk the land at night. Not to mention unwelcome visitors in the form of the mysterious magician Thaddeus, and the ever-present Inspector Jones, just waiting for them to slip up.

Meanwhile, Tess finds herself struggling with a terrifying face from the past - but can this be the clue which unlocks the mystery of Flint Hall?

"A terrifying, thrilling, almost non-stop journey into magic, privilege, and mystery. Absolutely brilliant."
