The Waters of Eternal Youth by Donna Leon - this latest instalment of the Commissario Brunetti series is slightly different, in that it isn't, for the most part, about a murder. Instead it's a bit of a cold case - at a tedious dinner party given by his in-laws, Brunetti is introduced to an elderly friend of his wife's mother, who wants him to find out what really happened some 15 years ago, when her grand-daughter was allegedly pushed into one of the canals and, although she was rescued, sadly she was underwater long enough to suffer brain damage, and as a result was left with the mental age of a 7 year old. After all this time, it's difficult to prove it was anything more than an accident (and not a suicide attempt as some have suggested); the man who rescued her was a known drunk back then, and is even more so now, but he is the only definite witness. But Brunetti does his best, and despite being thwarted at pretty much every turn, he persists. This is another enjoyable book, with some nice dry humour, and plenty of food too! It's quite languid, but there are a few twists later on, and Brunetti and his family and colleagues (well some of them anyway) are likeable as ever. 8/10
