Tim Bradford seems the sort of bloke you'd sit down with in the pub for a quiet pint, but end up having a mammoth beer session with instead, and a good laugh too. Although this is a hugely informative book about London's hidden rivers, it thankfully shuns the customary po-faced format of history texts and laces it instead with tales of lost Danish punk bands, elusive hardline feminist river walkers, water-hexed football stadia and much (maybe too much judging by some of the author's off-theme theories) extra strength lager as a dowsing tool.
But its real strength, on top of the excellent cartoons and etchings that break up the words, lies in its depiction of latter-day London. As Bradford wanders the streets on rainy days looking for glimpses of long forgotten ditches, he bumps into all kinds of bums, dropouts and drinkers that are as much a part of the capital's hidden fabric as the streams of yore he professes to be seeking.
For me, this book combined the perfect reading experience - laughter and learning.
