Peter Ackroyd's Hawksmoor was first published in 1985. Alternating
between the eighteenth century, when Nicholas Dyer, assistant to
Christopher Wren, builds seven London churches that house a terrible
secret, and the 1980s, when London detective Nicholas Hawksmoor is
investigating a series of gruesome murders on the sight of certain old
churches, Hawksmoor is a brilliant tale of darkness and shadow.
