44 Scotland Street

Long-suffering child genius Bertie Pollock has much to contend with in the latest instalment of life at 44 Scotland Street, not least the birth of his brother Ulysses. Bertie had hoped that caring for a new baby would command all of his mother's attention, but he quickly sees that his dream of being left to his own devices is not destined to come true.

Despite inhabiting a great city renowned for its impeccable restraint, the extended family of 44 Scotland Street is trembling on the brink of reckless self-indulgence. Matthew and Elspeth receive startling – and expensive – news on a visit to the Infirmary, Angus and Domenica are contemplating an Italian ménage a trois, and even Big Lou is overheard discussing cosmetic surgery.

To the casual observer, the great enlightened city of Edinburgh, home of no-nonsense sermons and cream teas, might appear immune to the rollercoaster of strong emotions. But at 44 Scotland Street, as Matthew and Elspeth embark on the risky enterprise of married love, the raffish portrait painter Angus Lordie has a premonition of disaster. Soon enough Irene Pollock is shocked to learn that her small son Bertie harbours a highly unsuitable ambition; and Angus finds himself facing a large Glaswegian gangster.

Amateur sleuth Isabel Dalhousie is a philosopher who uses her training to solve unusual mysteries. She edits the Review of Applied Ethics, addressing such questions as "Truth telling in sexual relationships", and she also hosts The Sunday Philosophy Club at her house in Edinburgh. Behind the city's Georgian facades, its moral compasses are spinning with greed, dishonesty, and murderous intent.

The art of love is never a science.: Meet Don Tillman, a brilliant yet socially inept professor of genetics, who’s decided it’s time he found a wife. In the orderly, evidence-based manner with which Don approaches all things, he designs The Wife Project to find his perfect partner: a 16-page, scientifically valid survey to filter out the drinkers, the smokers, the late arrivers. Yet, Rosie Jarman possesses all these qualities and. Don easily disqualifies her as a suitable candidate (even if she is "quite intelligent for a barmaid").

If you've got a problem, and no one else can help you, then pay a visit to Precious Ramotswe, Botswana's only - and finest - female private detective. Her methods may not be conventional, and her manner not exactly Miss Marple, but she's got warmth, wit and canny intuition on her side, not to mention Mr J.L.B. Maketoni, the charming proprietor of Tlokweng Road Speedy Motors.

The life of 79-year-old pensioner Peggy Smart is as beige as the décor in her retirement village. Her week revolves around aqua aerobics and appointments with her doctor. Following a very minor traffic accident, things have turned frosty with her grown-up children, and she is afraid they are trying to take away her independence. Noticing her memory isn't what it used to be, Peggy is taking ever more inventive steps to cover up her dwindling faculties.

Alexander McCall Smith, best-selling author of The No. 1 Ladies' Detective Agency, has turned his hand to humour. The delightful result is a creation of comic genius. For in the unnaturally tall form of Professor Doctor Moritz-Maria von Igelfeld, we are invited to meet a memorable character whose sublime insouciance is a blend of the cultivated pomposity of Frasier Crane and of Inspecteur Clouseau's hapless gaucherie.

Summer in Edinburgh is a season of delicate sunshine and showers, picnics with loved ones in blossoming gardens and genteel celebrations of art and music. But Isabel Dalhousie's peaceful idyll is broken when a single meeting over coffee with fellow philosopher Dr George McLeod brings an irate phone call from his wife, Roz, who implacably accuses Isabel of conducting an affair with her husband.

What happened to Jacques Gaillard? The brilliant teacher at the École Nationale d’Administration, who trained some of France’s best and brightest as future prime ministers and presidents, vanished ten years ago, presumably from Paris. This ten-year-old mystery inspires a bet—one that Enzo Macleod, a biologist teaching in Toulouse, France, instead of pursuing a brilliant career in forensics back home in Scotland, can ill afford to lose.

A missing private investigator is found locked in a car hidden deep in the woods. Worse still - both for his family and the police - the body was in an area that had already been searched 10 years ago. Detective Inspector Siobhan Clarke is part of a new inquiry, combing through the mistakes of the original case. There were always suspicions over how the investigation was handled, and now - after a decade without answers - it's time for the truth.

It's Christmas 1909, and for once Lady Hardcastle - respectable gentlewoman, amateur spy - and her lady's maid, Florence Armstrong, are setting sleuthing aside. They are invited to the festivities up at The Grange, as guests of Sir Hector and Lady Farley-Stroud. But barely have corks been popped and parlour games played when a mysterious crime comes to light.

An endearing stand-alone story from best-selling author Alexander McCall Smith. Val was working as a land girl when the Americans arrived at the nearby airfield in 1944. Mike, a young American airman, came into her life soon after, and so, too, did Peter Woodhouse, a dog badly treated on a neighbouring farm and taken in by her aunt. Little persuasion was needed for Mike to take Peter Woodhouse to the airbase, and over time he became the mascot of the American squad.

You'll be wincing in recognition and scratching your head in incredulity, but like Marian herself you won't be able to stop laughing at the sheer delightful absurdity that is modern life - because each and every one of us is clearly making it up as we go along. She has wonderful and tickling words of advice for those fast approaching 50.

The discovery of a dead body in the woods on Thanksgiving Weekend brings Chief Inspector Armand Gamache and his colleagues from the Surete du Quebec to a small village in the Eastern Townships. Gamache cannot understand why anyone would want to deliberately kill well-loved artist Jane Neal, especially any of the residents of Three Pines - a place so free from crime it doesn't even have its own police force.
