Although a bit of back story is given, I had missed some key events -- namely that Mort's daughter, Allie, had been back, was supposed to have been kept safe by the Fixer (Lydia), but she had been kidnapped? had escaped? to be with a billionaire Russian gangster. Mort and Lydia had been trying to find her again, and they thought she might be in London, but had set it aside for the time being.
A young girl's body is found; she had been tortured before her death. During the course of the investigation into this murder, another girl is killed. Both victims had ties to a loan company that charged exorbitant interest -- and when the money could not be paid -- had been lured into prostitution. That was bad enough, but new connections indicate that this may have even turned out worse for those two girls -- perhaps a snuff killing? If so, who was ordering these, and who had set up this prostitution scheme? Many questions for Mort and Lydia to tackle as they delve into a convoluted and deadly business that may lead them to tie up some other loose ends.
This was fast paced and entertaining and although suspenseful, there just isn't enough real depth to the main characters (despite what I know of their backgrounds) to give me more than a superficial interest in their future stories. I'll likely read #5 whenever it's released, but I think the "Justice" concept is only barely part of the whole plot at this point in the series.
Thank you to NetGalley and Alibi for the e-book ARC to review.
