The Kalahari Typing School for Men, Alexander McCall Smith

In the fourth instalment of The No. 1 Ladies Detective Agency series, our traditionally built heroine Mma Ramotswe waits for her fiancè to name a wedding date:

Would Mr J.L.B. Matekoni get round to naming a wedding date? She hoped so, although he certainly seemed to be taking his time. Perhaps they could get married in heaven, if he left it too late. That would certainly be cheaper.

and watches with some anxiety when a new detective agency comes to town:

It was not hard to find the Satisfaction Guaranteed Detective Agency. A large sign was painted in red letters: Experienced staff. Ex-CID. Ex-New York. Ex-cellent!
'Ex-CID,' said Mma Ramotswe. 'A retired policeman then. That is not good news for us. People will love the idea of taking their problems to a retired policeman.'
'And ex-New York,' said Mma Makutsi admiringly. 'That will impress people a great deal. They have seen films about New York detectives and they know how good they are.'
Mma Ramotswe cast a glance at Mma Makutsi. 'Do you mean Superman?' she asked.
'Yes,' said Mma Makutsi. 'That sort of thing. Superman.'
Mma Ramotswe opened her mouth to say something to her assistant, but then stopped... There was no point in arguing about Superman with Mma Makutsi. Whoever had opened this agency, even if they were really ex-New York, would hardly be Superman.

In the meantime, Mma Makutsi begins a new business venture, The Kalahari Typing School for Men, little realising that her star pupil is involved in a case that Mma Ramotswe has been hired for. It's another hot day in Botswana, another mystery for Mma Ramotswe to solve and another charming novel from Alexander McCall Smith.
