In Inspector Montalbano’s coastal town of Vigàta, a surge of migrants have been coming in by boat, and all the town’s hands are on deck to help the arrivals. At the heart of the scene are the police - on the lookout for the people smugglers responsible - and long night shifts are rendering Inspector Montalbano and his officers exhausted. Then one night, while Montalbano is enduring yet another gruelling stint at the port, a separate crime is committed - unexplained, unexpected, and unpleasant. Elena, the dressmaker at the town’s famous tailors, has been found dead....

On what should be a quiet Sunday morning, Inspector Montalbano is called to a murder scene on the Sicilian coast. A man has discovered his father dead in his Vigàtan beach house: his body slumped on the dining room floor, his morning coffee spilt across the table, and a single gunshot wound at the base of his skull.

Inspector Montalbano is awake at dawn, sitting on his porch, when his attention is caught by a seagull that falls from the sky, performing a strange dance, before lying down to die. Montalbano is perplexed by what he has witnessed and the scene hangs over him like an omen. About to depart for a holiday with his girlfriend Livia, Montalbano makes a quick trip to the police station to tie up loose ends. But when his dear colleague Fazio is discovered missing, Montalbano instead launches a desperate search for his lost friend....

When members of Vigata’s elite are targeted in a series of perfectly executed burglaries, Inspector Montalbano reluctantly takes the case. It isn’t long too before Montalbano finds himself taken with one of the victims, the captivatingly beautiful young Angelica. But as the detective’s attraction grows, a series of strange, anonymous letters claiming responsibility for the thefts begin to arrive.

As a favour to his wealthy father-in-law, the Count Falier, Commissario Guido Brunetti agrees to investigate the seemingly innocent wish of the Count’s best friend, the elderly and childless Gonzalo, to adopt a younger man as his son. Under Italian inheritance laws, this man would become the sole heir to Gonzalo’s substantial fortune, something which Gonzalo’s friends, including the Count, find appalling. For his part, Brunetti wonders why they're so intent on meddling in the old man's business.

Inspector Montalbano rises one morning to find the carcass of a horse on the beach in front of his seaside home. But no sooner do his men arrive than the body has mysteriously vanished, leaving only a track in the sand. Before long Rachele, a beguiling equestrian champion, turns up at police headquarters to report her horse missing. The horse had been stabled at the grounds of a certain Saverio Lo Duca, one of the richest men in Sicily. Lo Duca has lost one of his own horses, too. Montalbano, his curiosity piqued, investigates....

Maybe a phrase, a line, a hint somewhere would reveal a reason, any reason, for the elderly couple's disappearance. They'd saved everything.... There was even a copy of the 'certificate of living existence', that nadir of bureaucratic imbecility.... What was the protocol, to use a word dear to government offices? Did one simply write on a sheet of paper something like 'I, the undersigned, Salvo Montalbano, hereby declare myself to be in existence', sign it, and turn it in to the appointed clerk?

Chief Inspector Montalbano is on enforced sick leave. But when a local girl goes mysteriously missing, the whole community takes an interest in the case. Why are the kidnappers so sure that the girl's impoverished father and dying mother will be able to find a fortune? The ever-inquisitive Montalbano steps in, to get to the heart of the matter in his own inimitable style.

He began swimming in slow, broad strokes. The sea smelled harsh, stinging his nostrils like champagne, and he nearly got drunk on it.... In a fraction of a second, Montalbano realized he'd struck a human foot. Somebody else was floating right beside him, and he hadn't noticed. 'Excuse me,' he said hastily, flipping back onto his belly and looking over at the other. The person beside him didn't answer, because he wasn't doing the dead man's float. He was actually dead.

The lazy, slow month of August at the height of the Sicilian summer is, Inspector Montalbano assures his girlfriend, Livia, as they prepare for a relaxing holiday in a villa he has found for them, far too hot for any murders to be committed. But when Livia's friends' young son goes missing, a chain of events is sparked which will certainly ruin the Chief Inspector's pleasant interlude. A secret apartment and a grisly find in an old trunk are just the beginning as Montalbano navigates his way though the case and copes with the heat.
