Hidden in Plain Sight by Jeffrey Archer (William Warwick #2)

Newly promoted, Detective Sergeant William Warwick has been reassigned to the drugs squad. His first case: to investigate a notorious south London drug lord known as the Viper.
But as William and his team close the net around a criminal network unlike any they have ever encountered, he is also faced with an old enemy, Miles Faulkner. It will take all of William's cunning to devise a means to bring both men to justice; a trap neither will expect, one that is hidden in plain sight . . .
Filled with Jeffrey Archer's trademark twists and turns, Hidden in Plain Sight is the gripping next instalment in the life of William Warwick. It follows on from Nothing Ventured, but can be read as a standalone story.
