With his characteristic warmth, inventiveness and brilliant wit, Alexander McCall Smith gives us more of the gloriously entertaining comings and goings at 44 Scotland Street, the Edinburgh townhouse. Six-year-old prodigy Bertie perseveres in his heroic struggle for truth and balanced good sense against his insufferable mother and her crony, the psychotherapist Dr Fairbairn, going as far as to make a short-lived bid for freedom on a trip to Paris with the Edinburgh youth orchestra.

The story revolves around the comings and goings at No. 44 Scotland Street, a fictitious building in a real street in Edinburgh. Immediately recognisable are the Edinburgh chartered surveyor, stalwart of the Conservative Association, who dreams of membership of Scotland's most exclusive golf club. We have the pushy Stockbridge mother, and her prodigiously talented five-year-old son, who is making good progress with the saxophone and with his Italian.

Once more, we catch up with the delightful goings-on in the fictitious 44 Scotland Street from Alexander McCall Smith. With customary charm and deftness, Alexander McCall Smith gives us another installment in this popular series, now running in its ninth season in the Scotsman. Anything could happen to Bertie and the gang....

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.

Even down to its well-set Georgian townhouses, Edinburgh is a hymn to measure and harmony. But on Scotland Street, domestic accord is in short supply. Matthew and Elspeth welcome three new arrivals, though the joys of multiple parenthood are somewhat lost due to sleep deprivation and the difficulties of telling their brood apart. Angus and Domenica are to marry, and Domenica has ambitious and disturbing plans for their living arrangements, especially when it appears that Antonia, in Italy recuperating from Stendhal Syndrome, may not return.
