"It's like ice cream, Mr Flynn," Bertie continued. "When you have ice cream, you need to eat it straight away, otherwise it melts. If there are people who haven't got any, you should share it, if you can."

When despair for the world grows, Bertie's theory of ice cream reminds us that it's the simple pleasures in life that we should hold onto. And everyone's favourite seven-year-old has a lot to put up with: at home, Irene is planning lessons on Irish Culture for Bertie; at school, he is forced to join Olive and Pansy's book group, and during a day out with his best friend Ranald Braveheart Macpherson, the boys find themselves unexpectedly invited to a wedding.

Meanwhile, Bruce's latest property venture goes horribly wrong after trying to move a flat's front door to give it a more prestigious address. At Nine Mile Burn, Matthew and the triplets try to adopt an unwillingly-vegan dog. And Sister Maria-Fiori dei Fiore Montagna discovers the missing part of the Stone of Scone in Drummond Place Gardens.

Filled with Alexander McCall Smith's trademark warmth and humour, this latest book in the series is a must-read.
