When the Duke of Purbeck throws a house party to celebrate his daughter's twenty-first birthday and present her with a family heirloom, nobody expects that the weekend will end in murder. The fabled Belsingham pearls have a history steeped in blood and slaughter dating back more than a century—and now it seems they've claimed another life, when the interfering and opinionated Professor Coddington is found dead in the library with the pearls clutched in his hand. It looks like a robbery gone wrong, but then why didn't the thief take the necklace? And how did he escape unnoticed, given that half the guests were seemingly wandering around the house at the time of the murder? House guest Freddy Pilkington-Soames has enough on his plate already, with a lecherous nuisance of a grandfather to keep an eye on, a girlfriend his mother disapproves of, and an ex-girlfriend who's engaged to another man but shows signs of changing her mind. But with a killer on the loose in the house, it's time to forget his own troubles and rise to the occasion—or risk a scandal that could destroy the reputation of his whole family.

When Douglas Westray, the son of an eminent aircraft manufacturer, is found shot dead in a locked room at a society ball, it seems obvious that it’s suicide—after all, he had two failed engagements behind him, and had lost the family firm a prestigious prize through his own neglect. But not everybody is convinced—including Freddy Pilkington-Soames, who soon discovers that there are still questions to be answered. Why was Douglas wearing the wrong shoes when he was found? What is the connection with a near-disaster at an air show? And was Freddy’s narrow escape from death under the wheels of a car an accident or something more sinister? Assisted by his old friend, the wayward and irrepressible Lady Gertie McAloon, and pestered at every turn by rival reporter Corky Beckwith, Freddy finds himself drawn into a world of sabotage, blackmail and shady deals which threaten to scupper the success of a new fighter plane before it even gets off the ground. But there’s more at stake than just money, and now it’s up to Freddy to untangle the clues and unravel the dark secret of a murderer who has already killed at least once and will think nothing of killing again.

It's 1929, and Ticky Maltravers is the toast of London high society, adored by everyone—or so it seems, until somebody poisons him over dinner. Now it turns out that numerous people with secrets to hide had every reason to wish him dead. But which of them murdered him? For Freddy Pilkington-Soames, newspaper reporter and man-about-town, the question hits a little too close to home, thanks to an unfortunate drunken encounter with Ticky's corpse which he'd much rather the police didn't find out about—and thanks also to his exasperating mother Cynthia's seeming determination to get herself arrested by tampering with the evidence. But a pretty girl with big blue eyes is demanding his help in solving the mystery, so what can he do but agree? Now all he has to do is hide the wrong clues, find the right ones, and unmask the murderer before the police discover what's really been going on. That ought to be easy enough. If only people didn't keep getting killed...

The ladies of Clerkenwell Central Hall are none too pleased at having their Temperance meetings disrupted by the rowdy Communists next door, but for Miss Olive Stapleton in particular, the uneasy coexistence proves fatal when she is found stabbed through the heart with a paper-knife. Enter Freddy Pilkington-Soames, who’s been recruited by British Intelligence to investigate a suspected Communist plot to stir up a general strike. Freddy thinks there’s more to Miss Stapleton’s death than meets the eye, but as he delves more deeply into the mystery it only becomes more puzzling. What is the connection between the murder and the coded newspaper advertisements? Is a Welsh firebrand politician really as harmless as he seems? And what does the beautiful wife of an Austrian revolutionary philosopher want from him? It all points to one thing: danger ahead. But time is running out, and Freddy must act fast to stop the conspirators, or risk becoming the unwitting pawn in a deadly game that threatens to bring the country to its knees.

When Hollywood star Dorothy Dacres plummets six floors from her hotel terrace on the night of her greatest triumph, it initially looks like a tragic accident.

And when cocaine is found in her room, it only complicates matters further. Soon Freddy is chasing across London on the trail of drug dealers, in reluctant company with his deadly rival Corky Beckwith, the most unscrupulous reporter in Fleet Street, who will do anything for a story. With the future of a film studio at stake, can Freddy find the culprit-and get one up on Corky-before he becomes the killer's next victim?
