After solving two of the cold cases from the book by Parisian journalist Roger Raffin, Scottish scholar and amateur detective Enzo MacLeod finds himself confronting a diagnosis of a terminal illness and attacks by someone out to destroy everything he cares about and frame him for murder, just as he launches a probe into the sixteen-year-old murder of a rent boy. (Mystery & Detective)

A promise made to a dying man leads forensics ace Enzo Macleod, a Scot who's been teaching in France for many years, to the study which the man's heir has preserved for nearly twenty years. The dead man left several clues there designed to reveal the killer's identity to the man's son, but ironically the son died soon after the father. So begins the fourth of seven cold cases written up in a bestselling book by Parisian journalist Roger Raffin that Enzo rashly boasted he could solve (he's been successful with the first three). It takes Enzo to a tiny island off the coast of Brittany in France, where he must confront the hostility of locals who have no desire to see the infamous murder back in the headlines. An attractive widow, a man charged but acquitted of the murder—but still the viable suspect, a crime scene frozen in time, a dangerous hell hole by the cliffs, and a collection of impenetrable messages, make this one of Enzo's most difficult cases.

When France's top chef, Marc Fraysse, summoned the world's press to make a shattering announcement, rumors abounded that he was about to lose one of his three coveted Michelin stars. Instead, on arrival at his remote restaurant on a volcanic plateau in central France, they were greeted with the news that the troubled genius had been murdered, and the message he intended to deliver was never made. Seven years on, the identity of his killer also remains an enigma. Enzo Macleod takes on his fifth cold case and delves into the big business and high stakes of French haute cuisine. As winter sets in, and snow gathers along a volcanic horizon, he retraces long cold footsteps across a remote hilltop. But unravelling the complex web of relationships that surrounded the brilliant and mercurial chef - a spurned lover, a jealous wife, an estranged brother, an embittered food critic—also leads to strange parallels with his own life. And in opening up this celebrated cold case, he finds himself reopening old wounds from his past.

In a sleepy French village, the body of a man shot through the head is disinterred by the roots of a fallen tree. A week later a famous art critic is viciously murdered in a nearby house. The deaths occurred more than seventy years apart. Asked by a colleague to inspect the site of the former, forensics expert Enzo Macleod quickly finds himself embroiled in the investigation of the latter. Two extraordinary narratives are set in train - one historical, unfolding in the treacherous wartime years of Occupied France; the other contemporary, set in the autumn of 2020 as France re-enters Covid lockdown. And Enzo's investigations reveal an unexpected link between the murders - the Mona Lisa. Tasked by the exiled General Charles de Gaulle to keep the world's most famous painting out of Nazi hands after the fall of France in 1940, 28-year-old Georgette Pignal finds herself swept along by the tide of history. Following in the wake of Da Vinci's Mona Lisa as it is moved from château to château by the Louvre, she finds herself just one step ahead of two German art experts sent to steal it for rival patrons - Hitler and Göring. What none of them know is that the Louvre itself has taken exceptional measures to keep the painting safe, unwittingly setting in train a fatal sequence of events extending over seven decades. Events that have led to both killings. The Night Gate spans three generations, taking us from war-torn London, the Outer Hebrides of Scotland, Berlin and Vichy France, to the deadly enemy facing the world in 2020.
