This week is a bit of a secularism special - punch your fist in the air at the Rally to Defend Freedom of Expression, find out about the perils of censorship in Nick Cohen's new book and get the accurate story on the Bideford council prayers ruling. Plus we talk about a new survey showing Christians aren't terribly Christian, find out why Alan Turing deserves a pardon and solve the mystery of which Sherlock Holmes adaption is best.
