The sixth Nic Costa novel, The Garden of Evil, is winning a rave reception from the critics, including coveted starred reviews from Publishers Weekly and Booklist, the magazine of the American Library Association. PW describes the work as ‘this dark jewel of a thriller’. Booklist’s Bill Ott declares, ‘Arturo Pérez-Reverte has long set the gold standard for mixing history, mystery, and modern life into literary stews of mouthwatering flavor and incredible subtlety, but it’s time to agree that Hewson now shares that position—and is on the verge of claiming it outright.’

The Daily Express describes it as ‘even more gripping that its predecessors’. Margaret Cannon, in the Toronto Globe & Mail, says the series is one of her favourites, and adds, ‘The Garden of Evil is the best book so far in the Costa series, and that’s saying a lot. But Hewson takes his plotting here a giant step further than in the usual cop/chase story.’

It was Book of the Month in this month’s Choice Magazine which said: ‘David Hewson is on top form with this novel, taking his readers on a gripping journey through the streets of the Eternal City’. Crimesquad, which makes David author of the month, gives the book a five-star review and says, ‘This is a heady concoction of classic crime novel elements, perceptive characterisation and illuminating historical detail, all set in exotic locations and brilliantly told by a master storyteller.’

Publishers Weekly (starred review)

At the outset of this dark jewel of a thriller, Hewson’s sixth to feature Roman detective Nic Costa (after The Seventh Sacrament), Costa and his team are just starting to process a crime scene in an artist’s shabby studio, where two corpses lie sprawled before a painting of a rapturous female nude redolent of Caravaggio, when they flush out a hooded gunman. The gunman escapes in the ensuing chase… While Costa is taken off the case, his rule-bending boss finds a way for him to help on the sly, assisting the unusual art expert—young Sister Agata Graziano—called in to investigate whether the canvas could really be a Caravaggio and what light it might shed on the murders. You don’t have to be much of a sleuth to foresee danger for Sister Agata, but that’s about the only predictable element in a plot otherwise as serpentine—and suspense filled—as the ancient Roman byways through which Costa stalks his prey.

Hewson’s latest Nic Costa thriller opens with a shocker that will have series fans reeling, just as it does the principal players: Rome police detectives Costa and Gianni Peroni and their boss, the brooding Leo Falcone. What follows is another gritty, compelling mix of mean streets and ancient history, as the detectives attempt to unravel an appalling series of murders that seems to connect to an unknown Caravaggio painting depicting a tableau of startling depravity.

With the help of lay sister and Caravaggio expert Agata Graziano, the detectives quickly determine that a group of wealthy Roman aristocrats, impervious to the law, are re-creating the violent, orgiastic lifestyle enjoyed centuries earlier by Caravaggio and his circle, who called themselves the “Ekstasists”—and if a few prostitutes die in support of the hedonists’ revels, what of it? As usual, Hewson mixes art history and contemporary crime perfectly, but this time he digs deeper, finding connections between art and life that go to the very heart of humanity’s conflicted cravings for the sensual and the spiritual. And emerging from the complex, masterful plot, its sinews intertwined between past and present, is the towering, tragic figure of Caravaggio, whose still-unsolved murder in Rome in 1606 holds the key to bringing the modern-day Ekstasists to justice.

Arturo Pérez-Reverte has long set the gold standard for mixing history, mystery, and modern life into literary stews of mouthwatering flavor and incredible subtlety, but it’s time to agree that Hewson now shares that position—and is on the verge of claiming it outright.

Margaret Cannon, in the Toronto Globe & Mail…

The Nic Costa series, set in Rome, is one of my favourites. Hewson sets his stories so firmly in place that it’s possible to go from street to piazza to alley, and almost feel the stones of the walks or touch the ancient Roman bricks. The Garden of Evil is the best book so far in the Costa series, and that’s saying a lot. But Hewson takes his plotting here a giant step further than in the usual cop/chase story.

The first chapter, The Little Death, sets the scene. A dapper widower named Aldo Caviglia heads out into his city. Aldo is a native Roman, well acquainted with the city’s history, arts, myths and mysteries. For most of his life, he was a baker. But when his wife died, he developed a drinking problem and lost his job. Since then, he’s made his living as a pickpocket. He specializes in lady tourists. His excellent English and perfect knowledge of streets and trams give him instant entrée to the lost and tired. He is careful, stealing only what he needs and passing a bit along to the poor.

On this day, Aldo “assists” a very attractive and unusual woman. After he lifts her wallet, he realizes she is ill and he has her medicine. He decides to go after her and return her belongings, but that decision, made all for the good, turns things very bad. The opening, building to a brilliant death scene, sets the stage for the rest of the book.

This is no ordinary murder, Nic Costa realizes at once. The woman Aldo robbed and followed was one of the foremost art experts in Europe, and she and Aldo are dead in front of a magnificent painting, an unknown Caravaggio that is worth millions.

Nic soon surmises why the victims were murdered, and by whom, but he can’t touch the killer, who is protected by money and lawyers. How will Costa, never content to play the quiet cop game, find justice for the dead?

The Garden of Evil is the sixth in the Costa series and is even more gripping than its predecessors. Hewson is a cunning storyteller… What follows is a deadly cat-and-mouse game during which the body count steadily rises and Roman history once again proves to be a vital component in the case. The Garden of Evil is impossible to put down.

Mike Ripley, in a review at Shots Magazine, writes…

Modern Italy has long been a popular location for crime novels written by non-Italians. I remember with great pleasure Reginald Hill’s Another Death In Venice from 1976 and the late Michael Dibdin, in his pre-Aurelio Zen days, cut his teeth with A Rich Full Death ten years later before going on to dominate the field. Many others have dipped a fork into the pasta sauce of Italian crime: the late Sarah Caudwell, the late Magdalen Nabb and, I hear you scream, Donna Leon. For my money, though, the best practitioner of this “outsider’s” art is Yorkshireman David Hewson who has been clocking up the plaudits with his series set in Rome featuring the cop duo Costa and Peroni. His new title is The Garden of Evil… and I have been privileged to read an advance copy and very good is it too.

A real twister of a tale, this is the sixth novel in Hewson’s atmospheric and addictive series.

David Hewson is on top form with this novel, taking his readers on a gripping journey through the streets of the Eternal City

The Citizen, South Africa….

A dark tale of murder, Renaissance-era art and secret cults set in the backstreets of modern-day Rome, this is an engrossing read. Rome is thoroughly explored, and it would be useful to be familiar with the city to have a better feel for the locations described. It’s very well written, not too descriptive and not too vague.
Hewson delivers his message clearly and with elegance. Exploration of Rome’s art history adds a fascinating sidetrack and a little more scholarly depth to what would otherwise be a straight-forward crime novel.

Harriet Klausner, one of America’s most prolific reviewers, says…

Filled with incredible but plausible twists, this is a strong Italian police procedural that will have the audience reading it in one suspense laden sitting. The story line is fast-paced as Costa works the streets of Rome seeking a killer who affirms death imitates art. David Hewson is at his best with this superb Roman thriller.
