The 4th book in the series sees Lorne rejoining the Met and investigating a series of brutal robberies/murders. Not only has she got a new job and a serious case to deal with, she's also worrying about her fiance, Tony, who's sent on a secret MI6 mission, 2 weeks before their wedding.
The plot and writing will draw you in instantly, and I think this is probably my favourite of the Justice series. I hope she'll be making a come back in the future! If you're looking for a fab fast-paced thriller, look no further.
