Fascinating documentary on BBC Radio 4 about architect Nicholas Hawksmoor and the stories around him (generally about him being an occultist, ordering his buildings around London along some series of significant axes) - familiar to anyone who's read Peter Ackroyd's Hawksmoor, Alan Moore's From Hell, and Iain Sinclair Lud Heat.
I'd say it was on this morning (and it was) but it's available online on our Radio 4 site for the next 7 days. Click the link below and check the 'D' section for Devil's Architect .. it'll be up for a while [in RealAudio]
UPDATE! Sorry, it's gone.
