The rains are coming, but not just yet. When they do, there will be green shoots of growth throughout Botswana. Pumpkins will flourish – particularly those of Mma Potokwani, matron of a children’s home and old friend of Precious Ramotswe. Mma Potokwani and Mma Ramotswe have many other things to talk about, including a new friendship that Mr J.L.B. Matekoni has struck up with Mr Freddie Mogorosi, a prominent figure in the motor trade. Freddie Mogorosi has invited Mr J.L.B. Matekoni to go fishing with him on the local dam – which is home to some fairly nasty crocodiles. They do not catch anything, but something nearly catches them.

In the meantime, Mma Ramotswe looks into what seems to be a straightforward matter involving a husband who thinks his wife may be having affair. But there is a surprise in store: she, it transpires, suspects that he himself has a lover. This is obviously a case that will require tact – which of course is a quality Mma Ramotswe has in abundance. Along with kindness.

For Botswana is a kind country, and in this latest visit to The No. 1 Ladies’ Detective Agency we are reassured that no matter how unhappy the world may be, there is always an oasis of courtesy and peace in that special place in southern Africa. To which you are now invited.

Meanwhile, at Tlokweng Road Speedy Motors, Mma Ramotswe’s husband, Mr J.L.B. Matekoni, gets a visit from a middle-aged client who wants to purchase a fast Italian sports car. What should the conscientious garagiste do in such circumstances? Should the client’s wife be told? Mma Ramotswe is used to wrestling with such tricky questions, but it is harder for Mr J.L.B. Matekoni.

And in the background is that beautiful country, Botswana, with its wide skies and its courteous people. In such surroundings, big problems soon seem small, and small worries fade away altogether.

‘You can’t go out of the house without tripping over a philosophical question.’ That is a remark made by Isabel Dalhousie to Jamie, the bassoonist who is her handsome younger husband. Isabel’s own life, of course, points to the truth of this observation: she seems to attract philosophical problems in much the same way as a magnet attracts iron filings.

In this latest movement in the symphony of her life, Isabel is faced with novel challenges, each of which tests her resolution to do the right thing. Dawn, a nurse in an infectious diseases ward, is let down by her lover and needs a place to live. Not surprisingly, Isabel offers her a roof over her head. What do you do, though if your house-guest locks herself away and avoids all contact?

And then there is the pompous and slippery Professor Robert Lettuce. He is planning a prestigious conference, and involves Isabel in it. But look at the budget: why is there such a large payment for Lettuce himself and for a young female assistant? Isabel is suspicious.

Other intriguing problems abound, including Isabel’s involvement in a book group threatened by discord and bickering. Isabel remains calm. Of course she does. She knows the power of love, reason, and a clear head to resolve all of these issues, and more.

PRAISE FOR THE ISABEL DALHOUSIE NOVELS:

‘Isabel Dalhousie’s charm is undeniable’ Sunday Times

‘The No. 2 Lady Detective . . . anyone who loves Precious cannot fail to be charmed’ Mail on Sunday

Professor Moritz-Maria von Igelfeld is not just any German professor – he is the author of that great work of scholarship, Portuguese Irregular Verbs. His eminence in language studies is widely recognised, even if it is rarely acknowledged by his colleague, Professor Detlev-Amadeus Unterholzer, author of a much less important work on the subjunctive. Their rivalry bubbles away under the surface, but is apt to come into the open if something unusual disturbs the calm waters of the institute in Regensburg in which they both work.

One such event is the arrival from New Orleans of two visiting scholars. These ladies, Professor Pom Pom Boisseau, and her friend, Professor Alice Martinique, are both experts in the Provençal language as well as being keen bikers. When they choose to arrive on large, noisy motorbikes, Unterholzer is shocked, but von Igelfeld is rather taken with Pom Pom. In fact, he is very taken with her, even to the extent of going for a ride with her on her motorbike.

Anybody can tell that this infatuation will lead to disappointment, if not worse. But for von Igelfeld, disasters often arrive in twos and threes. The great professor is invited to attend a student occasion in which the old habit of duelling rears its head. He is handed a sword…

Von Igelfeld may suffer humiliation after humiliation, but at the end of it all there is the promise of a visit to Louisiana, a culinary paradise, where important research is being undertaken into communication among oysters.

Meanwhile, at Tlokweng Road Speedy Motors, Mma Ramotswe’s husband, Mr J.L.B. Matekoni, gets a visit from a middle-aged client who wants to purchase a fast Italian sports car. What should the conscientious garagiste do in such circumstances? Should the client’s wife be told? Mma Ramotswe is used to wrestling with such tricky questions, but it is harder for Mr J.L.B. Matekoni.

And in the background is that beautiful country, Botswana, with its wide skies and its courteous people. In such surroundings, big problems soon seem small, and small worries fade away altogether.

If you are the founder and Managing Director of the No. 1 Ladies’ Detective Agency you may expect complete strangers to approach you with their problems when they see you having dinner with your husband in a peri-peri restaurant. And if you are Precious Ramotswe, you are a kind and helpful person who will be willing to take on a quest to find the relatives of a man who, many years ago, left the country for the uncertainties and dangers of a distant conflict.

While that is going on, though, there may be other things that claim your attention – such as the shocking news that a club that calls itself the Cool Singles Evening Club is encouraging married men to pretend to be single and meet women under false pretences. Who can be behind such a distasteful venture? Mma Ramotswe shows great tact in dealing with this situation, and avoids harm to the innocent.

And all the time, she and her assistant, Grace Makutsi, are getting on with their normal lives – which, of course, include birthdays and the buying of birthday presents. A new dress makes a fine present, but not if, when being tried on, it splits in a way that is thought to be irreparable. Mma Potokwani has dealt with situations far worse that, and in dealing with this local emergency she shows her characteristic wisdom. At the end of the day, disaster is averted. Life in Botswana, that far and lovely country of the title, continues smoothly, which is what Mma Ramotswe and her friends want – and most certainly deserve.

Glasgow for Bertie is the promised land. The city of pies and Irn Bru, far from his controlling mother, Irene – his place of escape. But how will he respond to the news of the proposed merging of Edinburgh and Glasgow? A new member of Bertie’s class at school is causing ripples in his social circle. She is called Galactica MacFee and is going to be a match for Olive and her lieutenant, Pansy. And, an incredible new discovery: a Pictish stone, that is said to have the first-know written poem carved into it is the talk of the town. But, when the poem is eventually translated, it is thought it is best to keep it under wraps. In this new instalment in the perennially popular 44 Scotland Street series, we are back in the world of Angus and Domenico, Bruce, Matthew and Elspeth, and, of course, Bertie and his friend Ranald Braveheart Macpherson.

The Department of Sensitive Crimes is downsizing in light of a recent downturn of sensitive crime, and staff members are wondering who among them will be transferred elsewhere. As the bickering between colleagues intensifies, Ulf tries his best to stay above the fray. But when Anna, a longtime friend and coworker, appears to blame him for an old case that went sideways, it seems she may be putting her own job prospects above their friendship.

In the midst of all this, Ulf embarks on an important inquiry: a man’s cabin has mysteriously disappeared and Ulf is tasked with finding out what happened. How exactly does one steal a house? And, more to the point, how does one track down a stolen house? Meanwhile, a promising veterinary treatment for deafness in dogs has been announced, and Ulf’s dog, Martin, might be the perfect patient.

This latest novel is another masterful, farcical installment in the series that defines the genre that Alexander McCall Smith is singlehandedly championing: Scandi blanc.

From a highly reluctant German spy who is drawn to an East Anglian nunnery as his only means of escape, to the strange tale of one of the Cambridge spy ring’s adventures with a Russian dwarf, these are Alexander McCall Smith’s intriguing and typically inventive stories from the world of espionage.
