Coming up the first in our London Calling season of World Book Clubs which will be going out each Saturday over the next four weeks.

In the run up to the London Olympic games we'll be discussing four novels which focus on different aspects of the United Kingdom’s colourful and historic capital city.

This week we talk to acclaimed novelist, biographer and critic Peter Ackroyd who will be discussing his haunting Whitbread prize-winning novel, Hawksmoor, with an audience at St George's Church, Bloomsbury.

St George's is the final church designed by lauded architect of the English Baroque, Nicholas Hawksmoor, a central and sinister figure in this compelling murder mystery set amongst the labyrinthine streets of 18th Century London.
