Every book tells a story! And the 70 titles in the Pocket Penguins series are emblematic of the renowned breadth of quality that formed part of the original Penguin vision in 1935, and that continues to define our publishing today. Together, they tell one version of the unique story of Penguin. Innocent House PD James has been writing extremely popular, highly praised crime novels for more than forty years, and Penguin is proud to publish them in paperback. Her most famous and enduring creation is the poet-detective Adam Dalgliesh, and in Innocent House - taken from Original Sin - he is confronted with a suspicious death and a puzzle at a respected publishing house.
