John Banville for The Lock-Up

Known as one of our greatest contemporary novelists and the winner of the 2005 Man Booker Prize, in recent years John Banville has been credited with elevating the detective novel to "new artistic heights."

He is the author of twenty novels, including The Book of Evidence, The Sea, and, most recently, the bestselling crime novels, Snow and April in Spain, both of which were shortlisted for the CWA Historical Dagger.

Now, the Sunday Times bestselling author joins us in the bookshop to discuss Strafford and Quirke's latest endeavour as they return for their most troubling case yet...

1950s Dublin.

In a lock-up garage in the city, the body of a young woman is discovered - an apparent suicide. But pathologist Dr Quirke and Detective Inspector Strafford soon suspect foul play.

The victim's sister, a newspaper reporter from London, returns to Dublin to join the two men in their quest to uncover the truth. But, as they explore her links to a wealthy German family in County Wicklow, and to investigative work she may have been doing in Israel, they are confronted with an ever-deepening mystery.

With relations between the two men increasingly strained, and their investigation taking them back to the final days of the Second World War, can they join the pieces of a hidden puzzle?
