Written very much in the same entertaining but informative style of the author's SPECTACULAR VERNACULAR and TUNNELS, TOWERS AND TEMPLES, David Long this time limits his focus to London's historic centre, exploring and photographing the literally hundreds of tiny alleyways and passages which still criss-cross the square mile centuries after the streets were first laid out. Like the previous two the result is engaging, readable, hugely well-informed, and along the way Long finds so much to detain the walker/reader - from Wren churches and ruins to atmospheric Victorian pubs, from secret gardens to some really strange survivors of a London which has otherwise been lost, and more fascinating relics of Victorian, Georgian, Medieval and even Roman London than you would believe could have survived. Now the good weather's here I'm definitely going to spend a few weekends tracking down the lot.
