Harriett Gilbert and her guests – comedian Isy Suttie and opera singer and broadcaster Beverley Humphreys - discuss favourite books by Carlos Ruiz Zafon, Ian McEwan and Daniel Keyes.

The Shadow of the Wind by Carlos Ruiz Zafon, which Beverly describes as a "love letter to literature."

Isy picks The Comfort of Strangers by Ian McEwan, a sinister tale of two couples in an unnamed European town, which she admits does not have a particularly happy ending.

Harriett chooses the story of a young man with learning difficulties whose intelligence is enhanced by a scientific procedure - Flowers for Algernon by Daniel Keyes.

First broadcast on BBC Radio 4 in March 2012.
