The Lawless and Tilley books are a series of crime novels by British author Malcolm Rose.
The stories follow the investigations of a scientifically minded, university graduate and fast track detective DI Brett Lawless and his partner, the athletic, art-loving DS Clare Tilley.
Also a common feature in Rose's books, science often pays a key role in catching criminals.
The seventh book, Flying Blind, ended with the breaking of Lawless and Tilley's partnership.
However, Brett soon proved them wrong by demonstrating how his scientific knowhow could help crack cases faster.
