This is not your ordinary crime thriller...set in the mid 1970s in London the style of writing, character building and overall plot comes across authentic. Following Tennison after a few years experience within the police force, readers are submerged back into a time period where gender inequality was commonplace. La Plante develops Tennison within the plot into a strong yet rational character who faces many typical issues facing young women, alongside the aberrant challenges of police work in London. The backdrop of the story surrounds the alarming presence of the IRA in London, and Tennison finds herself involved in more ways than she would like! A thrilling easy-to-read book that I just could not put down.
